In this work we analyze the statistical thermodynamic functions and magnetic moment of a Dice lattice subject to a normal quantizing magnetic field. Our analysis addresses the Grand Potential and Helmholtz Free Energy, as well as the magnetic moment, entropy and specific heat at constant volume, explicitly determining their magnetic field dependencies in the degenerate statistical regime, replete with de Haas-van Alphen oscillatory phenomenology (and other magnetic field dependence); and also determining their temperature dependencies jointly with magnetic field features in the approach to the zero temperature limit. Furthermore, we evaluate the Grand Potential exactly, for arbitrary temperature and density. Our results are obtained with consideration of the presence of heat and particle baths with fixed chemical potential and they are discussed in relation to other pertinent work on the subject.

This study investigated the electrical properties of AlGaN/GaN high-electron-mobility transistors (HEMTs) with varied recess depths under the gate electrode. We demonstrated a recess depth of approximately 6 nm, which was achieved through neutral beam etching (NBE) technique with a low etch rate of 1.8 nm/min, resulting in device enhancement-mode (E-mode) behavior with threshold voltage (V th ) of 0.49 V. The effects of post-metallization annealing (PMA) on the device performance were also examined. The results revealed that PMA treatment improves the DC characteristics of the devices, including maximum drain current (I DMAX ), transconductance (g m ), subthreshold swing (SS), on-off ratio, and off-state leakage current, with maximum enhancement percentage of 18.3% for I DMAX , 3758% for on-off ratio, and 54.3% for SS. Moreover, this study compared the recess depths of metal-insulator-semiconductor high-electron-mobility transistors (MIS-HEMTs) with the SiN dielectric layer. The results showed that MIS-HEMTs exhibit more negative V th values, which can be attributed to the controlled surface states achieved through passivation.

The ever increasing field of application of nanodielectrics in electrical insulations calls for description of the mechanisms underlying the performance of these systems and for identification of the signs exposing their aging under high electric fields. Such approach is of particular interest to electrically insulating polymers because their chemical defects are of deleterious nature for their electrical properties and can largely degrade their performance at high electric fields. Although these defects usually leave spectroscopic signatures in terms of characteristic luminescence peaks, it is nontrivial to assign, in an unambiguous way, the identified peaks to specific chemical groups or defects because of the low intensity of the signal with the main reason being that the insulating polymers are weakly emitting materials under electric field. In this work, we go beyond the conventional electroluminescence technique to record spectroscopic features of insulating polymers. By introducing a single plane of silver nanoparticles (AgNPs) at the near-surface of thin polypropylene films, the electroluminescent signal is strongly enhanced by surface plasmons processes. The presence of AgNPs leads not only to a much higher electroluminescence intensity but also to a strong decrease of the electric field threshold for detection of light emission and to a phase-stabilization of the recorded spectra, thus improving the assignment of the characteristic luminescence peaks. Besides, the performed analyses bring evidence on the capability of AgNPs to trap and eject charges, and on the possibility to adjust the energetics of charge carriers in electrically insulating polymers at the electrode/dielectric contact via AgNPs.

Convolutional neural networks (CNNs) offer potentially a better accuracy alternative for conventional deep learning tasks. The hardware implementation of CNN functionalities with conventional CMOS based devices still lags in area and energy efficiency. This has necessitated the investigations of unconventional devices, circuits, and architectures to efficiently mimic the functionality of neurons and synapses for neuromorphic applications. Spin-orbit torque magnetic tunnel junction (SOT-MTJ) device is capable of achieving energy and area efficient rectified linear unit (ReLU) activation functionality. This work utilizes the SOT-MTJ based ReLU for activation and max-pooling in a single unit to eliminate the need of dedicated hardware for pooling layer. Moreover, 2 × 2 multiply-accumulate-activate-pool (MAAP) is implemented by using four activation pairs each of which is fed by the crossbar output. The presented approach has been used to implement various CNN architectures and evaluated for CIFAR-10 image classification. The number of read/write operations reduce significantly by 2X in MAAP based CNN architectures. The results show that the area and energy in MAAP based CNN is improved by at least 25% and 82.9%, respectively, when compared with conventional CNN designs.

The performance of silicon-based transistors is reaching its limit, and new materials like carbon nanotubes (CNTs) have started emerging to replace them in electronic products. However, the precise manipulation of CNTs requires complicated techniques, which increases process variation. These variations can lead to a decrease in the overall yield of the field-effect transistor (FET). This study shows how a low-frequency signal may regulate the number of CNTs on electrodes with a nanometer scale. We also demonstrate using an interdigitated electrode to reduce the shorts caused by metallic CNTs. The fabricated CNFETs were characterized using SEM, AFM, and I-V measurements. The study also demonstrates how the duration and amplitude of the applied signal impact the density of CNTs on the electrodes. Finally, finite element analysis was used to evaluate the electric field parameters during DEP. This technique will lead to precise CNTs per unit area, which can help fabricate transistors, sensors, and other electronic components.

Nanoparticles containing thrombolytic medicines have been developed for thrombolysis applications in response to the increasing demand for effective, targeted treatment of thrombosis disease. In recent years, there has been a great deal of interest in nanoparticles that can be navigated and driven by a magnetic field. However, there are few review publications concerning the application of magnetic nanoparticles in thrombolysis. In this study, we examine the current state of magnetic nanoparticles in the application of in vitro and in vivo thrombolysis under a static or dynamic magnetic field, as well as the combination of magnetic nanoparticles with an acoustic field for dual-mode thrombolysis. We also discuss four primary processes of magnetic nanoparticles mediated thrombolysis, including magnetic nanoparticle targeting, magnetic nanoparticle trapping, magnetic drug release, and magnetic rupture of blood clot fibrin networks. This review will offer unique insights for the future study and clinical development of magnetic nanoparticles mediated thrombolysis approaches.

We examine the question “Can Dirac materials exist in a nondegenerate statistical state?,” deriving and employing an identity for the thermodynamic Grand Potential $Omega$ (per unit volume/area) in the low density nondegenerate statistical regime, relating it to the density $n$ as $Omega = -beta ^{-1} n$ ( $beta ^{-1} = kappa _{B} T$ is thermal energy, $kappa _{B}$ is the Boltzmann constant, and $T$ is Kelvin temperature). The implications of this identity for Dirac materials are explored. The identity is universally valid for all thermodynamic systems in equilibrium in the nondegenerate, low density statistical regime, irrespective of size, dimensionality or applied static fields. Phenomena that may contribute to the realization of such a nondegenerate statistical equilibrium state in Dirac materials are discussed.

Most greenhouse gases come from biological activities and industry which will lead to global warming and show an impact on human life. With the need of green transformation of the global economic structure and seeking for higher quality of human life, the detection and management of greenhouse gases, as well as most hazardous gases in the environment, are increasingly demanding. Applications in different fields require sensors that can detect gas volume fractions with magnitudes from 10–9 to 10–4. Greenhouse gas detection plays an important role both in the agriculture and industry field. In this review, we first summarize the mechanism of several common gas detectors used currently. Then, the advantages of nanostructured gas sensors are discussed. Finally, the applications of infrared gas sensors based on nanophotonic devices are described in detail. This review has been an outlook on the future development of infrared gas sensors based on nanophotonic devices.
