We report on the design, fabrication, and characterization of the first interband tunnel junctions showing forward tunneling characteristics in the III-Nitride system. We have achieved record forward tunneling currents (>100 mA/cm2 at 10 mV, and > 10 A/cm2 peak current) using polarization engineered GaN/InGaN/GaN heterojunction diodes. We also report for the first time, negative differential resistance in interband III-Nitride tunnel junctions, with peak-valley current ratio (PVCR) of up to 5 at room temperature, and 147 at low temperature. Interband tunnel junctions can be utilized to connect multiple active regions devices such as multiple active region emitters and multi junction solar cells, which require efficient reverse tunneling and forward tunneling respectively. Efficient inter-band tunneling has been a challenge in III-Nitrides mainly due to the large band gaps found in this material system, which reduce tunneling probability. Recently, the unique property of polarization in III-nitrides was used to engineer band bending over smaller distances in nitride heterostructures to enhance tunneling [1, 2, 3], and we recently demonstrated a p-GaN/InGaN/n-GaN backward diode with record current density of 118 A/ cm2 at a reverse bias of 1 V where a thin high indium composition InGaN well was used to enhance tunneling between GaN regions [3]. Tunnel junctions are a critical component of multiple junction solar cells, and there is an interest to exploit the large band gap range of III-nitrides in such devices. However, such an application would require forward, rather than reverse tunnel diodes. In this work, we use polarization engineering to design and demonstrate the inter-band forward tunneling diodes with the high current density and low forward voltage drop.
我们报道了在iii -氮化物系统中显示正向隧道特性的第一个带间隧道结的设计、制造和表征。我们使用极化工程GaN/InGaN/GaN异质结二极管实现了创纪录的正向隧道电流(在10 mV时>100 mA/cm2,峰值电流>10 A/cm2)。我们还首次报道了带间iii -氮化物隧道结的负差分电阻,其峰谷电流比(PVCR)在室温下高达5,在低温下高达147。带间隧道结可用于连接多有源区器件,如多有源区发射器和多结太阳能电池,这分别需要高效的反向隧道和正向隧道。在iii -氮化物中,有效的带间隧穿一直是一个挑战,主要是因为这种材料体系中存在较大的带隙,这降低了隧穿的可能性。最近,iii -氮化物中独特的极化特性被用于在氮化物异质结构中设计更小距离的能带弯曲以增强隧道效应[1,2,3],并且我们最近展示了一个p-GaN/InGaN/n-GaN反向二极管,在1 V的反向偏置下,其电流密度达到118 a / cm2,其中使用了薄的高铟成分InGaN井来增强GaN区域之间的隧道效应[3]。隧道结是多结太阳能电池的关键组成部分,在这种器件中利用iii -氮化物的大带隙范围是一个有趣的研究方向。然而,这样的应用将需要正向,而不是反向隧道二极管。在本工作中,我们利用极化工程设计并演示了具有高电流密度和低正向压降的带间正向隧道二极管。

Devices for high performance computing beyond 14nm node - is there anything other than Si? 14nm节点以上的高性能计算设备——除了Si,还有其他的吗?

A scaling path for Si based technology seems possible to the 8nm node. Power limitation will force to reduce the supply voltage at the expense of device performance and susceptibility to process variations. A lower limit of Vdd=0.5V seems feasible. Parallelism on system level will provide system through put which stresses architecture and software development. In particular legacy code will be a problem for a transition period that might require dual supply multi core architectures. In this scenario device technology has to cater to both high voltage and low voltage operation. Beyond the 8nm node new device concepts are needed. Considering the time frame of a 2019 manufacturing for this node a device has to be demonstrated now. At this point CNTs seem to be the only viable option for the post Si area.
在8nm节点上,硅基技术的缩放路径似乎是可能的。功率限制将迫使以牺牲器件性能和对工艺变化的敏感性为代价来降低电源电压。下限Vdd=0.5V似乎是可行的。系统级的并行性将提供强调体系结构和软件开发的系统通道。特别是遗留代码在过渡时期将成为一个问题,因为这可能需要双电源多核架构。在这种情况下,器件技术必须同时满足高压和低压操作。除了8nm节点之外,还需要新的器件概念。考虑到2019年制造该节点的时间框架,现在必须展示设备。在这一点上,碳纳米管似乎是后Si区域唯一可行的选择。

We report results from a 130nm Indium Phosphide (InP) double heterojunction bipolar transistor (DHBT) technology. A 0.13×2µm2 transistor exhibits a current gain cutoff frequency ft >520GHz, with a simultaneous extrapolated power gain cutoff frequency fmax>1.1THz. The HBTs exhibit these RF figures-of-merit while maintaining a common-emitter breakdown voltage BVCEO=3.5V (JE=10µA/µm2). Additionally, scaling of the emitter junction length to 2µm enables high device performance at low total power levels. Transistors in the InGaAs/InP material system have demonstrated the highest reported transistor RF figures-of-merit. Previous published results include strained-InGaAs channel high-electron mobility transistors (HEMTs) with fmax of >1THz [1,2], and InP DHBTs with fmax >800GHz [3]. High bandwidth DHBTs have applications in a number of RF and mixed-signal applications due to their high power handling and high levels of integration relative to HEMTs. The HBTs reported in this work are designed for transceiver applications at the lower end of the THz frequency band [0.3–3 THz].
我们报告了一种130纳米磷化铟(InP)双异质结双极晶体管(DHBT)技术的结果。0.13×2µm2晶体管的电流增益截止频率ft >520GHz,同时外推功率增益截止频率fmax>1.1THz。在保持共发射极击穿电压BVCEO=3.5V (JE=10µa /µm2)的情况下,HBTs表现出这些射频性能指标。此外,将发射极结长度缩放至2 μ m,可在低总功率水平下实现高器件性能。InGaAs/InP材料系统中的晶体管显示出最高的晶体管射频性能。先前发表的结果包括fmax >1THz的应变ingaas通道高电子迁移率晶体管(hemt)[1,2]和fmax >800GHz的InP dhbt[3]。高带宽dhbt由于其高功率处理和相对于hemt的高集成度,在许多RF和混合信号应用中得到了应用。本工作中报道的hbt是为太赫兹频段(0.3-3太赫兹)低端的收发器应用而设计的。

Tunnel field-effect transistors (TFETs) are under intense investigation for low-power applications because of their potential for extremely low subthreshold swing (SS) and low off-state leakage [1]. III–V semiconductors with small effective mass and near broken band alignment are considered to be ideal for TFETs in that they promise high on-current and ION/IOFF ratios [2–3]. In this paper, we report the first demonstration of an InAs/Al0.45Ga0.55Sb heterojunction TFETs fabricated using an optical-lithography-only, self-aligned process and also investigate the effects limiting the InAs/Al0.45Ga0.55Sb TFET performance.
隧道场效应晶体管(tfet)由于具有极低的亚阈值摆幅(SS)和低的关闭状态泄漏的潜力,在低功耗应用中受到了广泛的研究[1]。具有小有效质量和近断带对准的III-V半导体被认为是tfet的理想选择,因为它们承诺高导通电流和离子/IOFF比[2-3]。在本文中,我们报道了首次使用光光刻,自校准工艺制备的InAs/Al0.45Ga0.55Sb异质结TFET,并研究了限制InAs/Al0.45Ga0.55Sb TFET性能的影响。

Protein nanopore-gated bio-transistor for membrane ionic current recording 用于膜离子电流记录的蛋白质纳米孔控生物晶体管

Although naturally occurring biological nanopores have shortcomings such as a relatively weak structural durability and a limited life-time, they are still intriguing candidates for nanobiosensing applications due to their sensitivity and specificity to analytes as well as various choices of ion channels depending on functionalities. In order to overcome limitations of biological nanopores, man-made solid-state nanopores have been explored. The fabricated solid-state nanopore is structurally durable and suitable for nanofabrication process yet it is still challenging to construct and a low throughput process, and lacks the chemical specificity of natural ion channels[1]. Can bionanotechnology be applied to improve this situation? Recent work has shown that nanomaterials (nanotubes, nanowires) can be gated by electrolyte, and even coated with lipid bilayers allowing charges of either the bilayer themselves[2]. These reports focus on time average changes in source/drain current due to gating by charges near the nanowire/nanotube. Thus, to date, no nanowire/nanotube device has been able to measure the time-dependent single ion channel recording.
尽管天然存在的生物纳米孔具有结构耐久性相对较弱和寿命有限等缺点,但由于其对分析物的敏感性和特异性以及根据功能选择的各种离子通道,它们仍然是纳米生物传感应用的有趣候选者。为了克服生物纳米孔的局限性,人们对人造固体纳米孔进行了探索。所制备的固体纳米孔结构耐用,适合纳米加工工艺,但其构建难度较大,工艺通量低,缺乏天然离子通道的化学特异性[1]。生物纳米技术可以改善这种状况吗?最近的研究表明,纳米材料(纳米管、纳米线)可以被电解质门控,甚至可以被脂质双分子层包裹,允许双分子层本身带电[2]。这些报告的重点是由于纳米线/纳米管附近的电荷门控引起的源极/漏极电流的时间平均变化。因此,到目前为止,还没有纳米线/纳米管设备能够测量随时间变化的单离子通道记录。

Modeling and simulation take an important role in the exploration and design optimization of novel devices. As the downscaling of electronic devices continues, the description of interfaces, randomness, and disorder on an atomistic level gains importance and continuum descriptions lose their validity. Often a full-band description of the electronic structure is needed to model the interaction of different valleys and nonparabolicity effects. NEMO 5 [1] is a modeling tool that addresses these issues and is able to provide insight into a broad range of devices. It unifies the capabilities of prior projects: multiscale approaches to quantum transport in planar structures in NEMO-1D [2], multimillion-atom simulations of strain and electronic structure in NEMO-3D [3] and NEMO-3D-Peta [4], and quantum transport in nonplanar structures in OMEN [5]. NEMO 5 aims at becoming a community code whose structure, implementation, resource requirements and license allow experimental and theoretical researchers in academia and industry alike to use and extend the tool.
建模和仿真在新型器件的探索和优化设计中起着重要的作用。随着电子设备的不断缩小,在原子水平上对接口、随机性和无序性的描述变得越来越重要,而连续体描述失去了其有效性。通常需要对电子结构的全波段描述来模拟不同谷和非抛物线效应的相互作用。NEMO 5[1]是一个解决这些问题的建模工具,能够深入了解各种设备。它统一了先前项目的能力:NEMO-1D平面结构中量子输运的多尺度方法[2],NEMO-3D[3]和NEMO-3D- peta[4]中应变和电子结构的百万原子模拟,以及OMEN非平面结构中的量子输运[5]。NEMO 5旨在成为一个社区代码,其结构,实现,资源需求和许可允许学术界和工业界的实验和理论研究人员使用和扩展该工具。

Experimental determination of dominant scattering mechanisms in scaled InAsSb quantum well 尺度InAsSb量子阱中主要散射机制的实验测定

Antimonide based compound semiconductors have gained considerable interest in recent years due to their superior electron and hole transport properties [1]. A Mixed anion InAsySb1−y quantum well heterostructure with high electron mobility of 13,300 cm2/Vs has already been demonstrated at a sheet carrier density of 2×1012 /cm2, albeit for a thick EOT quantum well (QW) structure [2]. A thin EOT structure is desired for improving short channel effects while maintaining the high electron mobility in the QW. In this paper, we study the low field electron transport properties in the high mobility InAs0.8Sb0.2 quantum well as we scale the QW heterostructure. Fig. 1(a),(b) show the schematic of the thick (TQW=12nm) and scaled (TQW=7.5nm) quantum well FET structure using InAs0.8Sb0.2 as channel material, In0.2Al0.8Sb barrier layer and an ultra-thin GaSb surface layer for avoiding surface oxidation of Al in the barrier [2]. Fig. 2(a),(b) show the simulated energy band diagram of the two structures using self-consistent Schrodinger-Poisson simulation, indicating strong electron confinement in the QW. The effect of nonparabolicity on thick QW with TQW=12nm has already been studied and an effective mass (m*) of 0.043m0 has been extracted experimentally [3]. For scaled QW the subband spacing was adjusted in order to achieve electron sheet charge density as a function of temperature, and the extracted density of states m*=0.05m0 was correlated to the transport effective mass. Experimental work to verify the obtained effective mass for scaled QW is underway.
近年来,基于锑化物的化合物半导体由于其优越的电子和空穴输运性质而引起了相当大的兴趣[1]。混合阴离子InAsySb1−y量子阱异质结构具有13,300 cm2/Vs的高电子迁移率,已经在2×1012 /cm2的载流子密度下被证明,尽管是厚EOT量子阱(QW)结构[2]。在保持高电子迁移率的同时,需要一种薄的EOT结构来改善短通道效应。本文研究了高迁移率InAs0.8Sb0.2量子的低场电子输运性质,并对量子阱异质结构进行了研究。图1(a)、(b)为采用InAs0.8Sb0.2作为通道材料、In0.2Al0.8Sb势垒层和超薄GaSb表面层以避免势垒中Al的表面氧化的厚度(TQW=12nm)和缩放(TQW=7.5nm)量子阱场效应管结构示意图[2]。图2(a)、(b)为采用自一致薛定谔-泊松模拟得到的两种结构的模拟能带图,表明量子阱中存在较强的电子约束。非抛物性对TQW=12nm的厚QW的影响已经被研究过,实验提取了0.043m0的有效质量(m*)[3]。对于缩放后的量子阱,调整子带间距以实现电子片电荷密度随温度的变化,提取的态密度m*=0.05m0与输运有效质量相关。验证所获得的有效质量的实验工作正在进行中。

Semiconducting nanowires (NWs) constitute an interesting platform as building blocks for various types of devices as well as for studies of fundamental material transport properties in one dimension. Nanowires have many interesting properties, such as the ability to incorporate strongly lattice-mismatched material combinations along its axis due to radial relaxation of interface strain. Furthermore, its inherent cylindrical geometry makes it an ideal candidate for devices implementing gates wrapped around the nanowire channel; the optimal geometry for maximum gate to channel coupling.
