MOSFETs with high-k and metal gate materials have been adopted nowadays. However, using traditional rapid thermal annealing as the annealing process after metal deposition causes thick SiO2 inter-layers and large flat-band shift. For future processes, an alternative post-metal annealing method has to be found. This study investigated electrical characteristics and physical properties of TiN/Al/TiN/HfO2/Si MOS capacitors annealed with a microwave annealing technique. The results show that samples annealed by microwave annealing at 2700W demonstrate low equivalent oxide thickness, low interface states density and low oxide trapped charge density. Besides, the diffusion of Al into oxides films is also suppressed. As a result, for high-k/metal gate MOS capacitors, high oxide capacitance, high breakdown voltage and low leakage current can be obtained using microwave annealing.

We have studied effects of deposition temperature on electrical properties of (ZnO)x(InN)1-x (ZION) films on ZnO templates. With increasing the deposition temperature from RT to 450°C, the electron mobility decreases from 93 cm2/Vs to 70 cm2/Vs and the carrier density increases from 1.8×1019 cm-3 to 3.4×1019 cm-3. Furthermore, we found a correlation between electrical properties and root mean square (RMS) roughness of the films. These results suggest the surface flatness is an important parameter to determine electrical properties of ZION films.

We report the fabrication of graphene quantum dots on Cu substrates by thermal CVD. The synthesized high-density graphene quantum dots exhibit strong surface enhanced Raman scattering (SERS) effects. The nanoscale distance of 30~50nm between neighboring quantum dots combined with quantum dots to form nanostructures favorable for plasmonic coupling enhanced high local electric fields, which lead to greatly enhanced strength of signal from Raman scattering of molecules on the substrate as an effective means of detecting, identifying, and measuring low concentration molecules of scientific and technological significance.

Because of their strong hydrophilicity, nanoporous silica materials are good candidates for humidity sensor applications. We employed molecular modeling to investigate the water behavior when confined in such materials in order to refine the design of the next generation of devices. We focused in this work on the mechanical behavior of those porous silica materials.

In this work, the deposition of 3-nm dispersed Zinc-Oxide (ZnO) nanoislands by thermal Atomic Layer Deposition (ALD) is demonstrated. The physical and electronic properties of the islands are studied using Atomic Force Microscopy, UV-Vis-NIR spectroscopy, and X-ray Photoelectron Spectroscopy. The results show that there is quantum confinement in 1D in the nanoislands which is manifested by the increase of the bandgap and the reduction of the electron affinity of the ZnO islands. The results are promising for the fabrication of future electronic and optoelectronic devices by single ALD step.

Small insects have agile performance in flight, walking locomotion, and so on. Currently, many researchers have been focusing the dynamics of their locomotion. We have been developing micro scaled piezoresistive force sensors to measure forces exerted by insects during flying, walking and jumping.

The use of biomimetic sensor has attracted attention due to its sensitivity and selectivity. Molecular imprinted polymer (MIP) among the best synthetic biomimetic interfaces to detect target molecules. However MIP has low electrical conductivity. Sensor fabricated using high conductive polymer will possess a good sensitivity and short response time. Therefore, it is important to enhance the conductivity of MIP, thus it would directly influence charge carrier mobility of the polymer itself. The resulting rGO-MIP OTFT exhibit electrical conductivity of 3.10×10-3 Sm-1 at 0.4wt/vol% and MIP exhibit electrical conductivity of 7.16×10-4 Sm-1. The electrical conductivity of rGO-MIP increased about one in magnitude order compared to MIP. Moreover, this work reports the electrical performance of reduce graphene oxide-molecular imprinted polymer organic thin film transistor (rGO-MIP OTFT) for serine detection. rGO was introduced into MIP, to allow a highly conductive sensing material thus enhanced selectivity and sensitivity of the sensor. By analyzing the electrical performance of the sensors, the performances of OTFT sensor enhanced with rGO-MIP interlayer and OTFT sensor with MIP interlayer when exposed to serine analyte were obtained. The results showed that there were remarkable shifts of drain current obtained from OTFT sensor with rGO-MIP interlayer after exposed to serine analyte. Moreover, the sensitivity of OTFT sensor with rGO-MIP interlayer was nearly higher than the OTFT sensor with MIP interlayer. Hence, it proved that rGO successfully enhanced the sensing performance of OTFT sensor.

We have grown ultrahigh-density self-assembled quantum dots (QDs) of InGaAs with sheet densities up to 2.5×1011 cm-2 and lateral diameters down to 10 nm, where the dot density increases with increasing As pressure during dot growth under optimum growth conditions. A ground-state photoluminescence (PL) spectrum shows a spectral width of 47 meV for the highest-density sample. Optical excitation-density dependences of the PL intensity and time profile are studied. The PL intensity from QD excited states increases with increasing excitation power, originating from a state-filling effect in QDs, which is directly confirmed by a plateau-like behavior on the PL decay curve. We find that the filling effect is significantly suppressed in the above ultrahigh-density dot ensemble, which suggests potential applications to superior energy-saving lasing and spin-functional optical devices.

Nanotool feeding system (NTFS) is presented for efficient nanomanipulation. We constructed a unique bio-nanomanipulation system inside an Environmental-SEM (E-SEM) using various nanotools, for example stiffness measurement nanotool, dual electrical nanoprobe, nanopicker, nanofork, nanocutter, nanoputter, and nanoinjector. For continues usage of different multiple tools, it needs to exchange the nanotools continuously. In this paper, the Rotary-table Nanotool Feeding System (R-NTFS) is proposed to realize continuous exchange of different multiple tools individually. An efficient continuous nanomanipulation was achieved by a short exchange time which was about 13 seconds. Finally, the multiple nanoinjection was demonstrated using the proposed R-NTFS.
