In this work, we present an effort to couple a three-dimensional (3-D) Monte Carlo Phonon Transport (MCPT) kernel with a 3-D Monte Carlo Electron Transport (MCET) simulator. The phonon-phonon scattering is modeled in relaxation time approximation (RTA) using Holland's formalism. Diffusive boundary collisions for phonons is modeled using the Beckmann-Kirchhoff (B-K) surface roughness scattering formalism considering the effects of phonon wavelength, incident angles and degree of surface roughness. In the electron-phonon coupled platform, acoustic and intervalley \u0000<italic>g\u0000 and \u0000<italic>f\u0000 type electron-phonon scattering mechanisms are considered and the resulting local temperature modification has been used to bridge the electron and phonon transport paths. The simulator has been validated by modeling the self-heating effect in a nanoscale FinFET device. Here, phonon transport at the oxide-silicon interface has been treated using the Diffuse Mismatch (DM) model, whereas, the phonons in the oxide have been described using the Debye model and temperature and frequency dependent relaxation time. For a FinFET with a gate length of 18 nm, channel width of 4 nm, and a fin height of 8 nm, simulation results show an ON current degradation of as high as ∼7% due to self-heating. The temperature rise in the channel region is found to be ∼30 K.","PeriodicalId":449,"journal":{"name":"IEEE Transactions on Nanotechnology","volume":"23 ","pages":"696-703"},"PeriodicalIF":2.1,"publicationDate":"2024-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142565514","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work reports an extensive investigation of a nanostructured surfactant such as Sodium Dodecyl Sulfate (SDS) and Cetyltrimethyl Ammonium Bromide (CTAB) activated mixed metal oxide (Zinc Oxide / Nickel Oxide) nanomaterial. The crystal study demonstrates an increase in the ZnO/NiO characteristic peaks (101) and (200), due to surface reactive agents. The increment of CTAB molar ratio has significantly increased the crystallite size, such that the bandgap of ZnO/NiO composite is reduced from 3.37eV to 2.80 eV. Brunauer-Emmitt-Teller (BET) surface area study revealed the production of a mesoporous ZnO with an improvement in the specific surface area from 7.82 to 52.01 m\u00002\u0000g\u0000−1\u0000 with a mean diameter reducing from 22.28 to 18.94 nm for the CTAB molar concentration range of 0.0, 0.5, 1.0, 1.5 and 2.0 M namely SC-1, SC-2, SC-3, SC-4, and SC-5 respectively. The internal resistance achieved for the 2M sample is 1 KΩ, which is suitable for better humidity and gas sensing properties. Hence, the proposed ZnO/NiO metal oxide material is more sensitive to a plurality of analytes by providing an increased BET surface area.","PeriodicalId":449,"journal":{"name":"IEEE Transactions on Nanotechnology","volume":"23 ","pages":"727-732"},"PeriodicalIF":2.1,"publicationDate":"2024-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142565515","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, implementing BN in hardware presents challenges due to the need for an additional complex circuit to normalize, scale and shift activations. We proposed a hardware binary neural network (BNN) system capable of BN in hardware, which is consist of an AND-type flash memory array as a synapse and a voltage sense amplifier (VSA) as a neuron. In this system, hardware BN was implemented using a voltage shifter by adjusting the threshold of the binary neuron. To validate the effectiveness of the proposed hardware-based BNN system, we fabricated a charge trap flash with a gate stack of SiO\u00002\u0000/Si\u00003\u0000N\u00004\u0000/SiO\u00002\u0000. The electrical characteristics were modelled by using BSIM3 model parameters so that the proposed circuit was successfully demonstrated by a SPICE simulation. Moreover, variation effects of the voltage shifter were also analyzed using Monte Carlo simulation. Finally, the performance of the proposed system was proved by incorporating the SPICE results into a high-level simulation of binary \u0000<italic>LeNet-5\u0000 for MNIST pattern recognition, resulting in the improvement of the proposed system in terms of power and area, compared to the previous studies.","PeriodicalId":449,"journal":{"name":"IEEE Transactions on Nanotechnology","volume":"23 ","pages":"677-683"},"PeriodicalIF":2.1,"publicationDate":"2024-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142434586","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They surpass conventional bulk MOSFETs in terms of subthreshold slope, leakage current and short channel effects. This paper presents a semi-analytical model accounting for both point tunneling and line tunneling schemes in a modified split-channel gate overlap source TFET(SC-GOSTFET) architecture. Considering both the tunneling schemes simultaneously along with the added line component enhances the ON-state current thus making the TFETs a better candidate for nano bio-sensors. The increase in length of the tunneling path is the major advantage of this hybrid model. This also helps to ameliorate the effect of quantum confinement in the band edges during band bending. The proposed biosensor shows reasonable agreement with the simulation data obtained from TCAD and 44.21% and 75.62% higher sensitivity over conventional biosensors.

Traditional waveguide grating antennas have large footprints, limiting antenna arrays' density. High diffraction efficiency is essential for effective signal transmission, making it a crucial aspect of antenna design. Optical antennas need higher diffraction efficiency, compact size, and broader field of view to achieve this. The proposed work aims to design a single-etch grating antenna on a silicon-on-insulator (SOI) platform that emits light off-chip. The methodology combines the initial grating antenna designed using Finite-difference time-domain (FDTD) simulations and optimizes it with a genetic algorithm. The proposed design uses a transverse spliced grating, Bragg reflectors, and bottom reflector to achieve an impressive upward diffraction efficiency of nearly 88% operating in C -band centered at 1550 nm. The size of the proposed antenna is 2.8 μm and offers a wide far-field beam width of 38 ° x 136 °.
