Abstract. We have systematically investigated the ballistic electron transport in gold and silver nanoribbons using first principle methods. The electronic structure calculation is carried out “density functional theory” (DFT) within “SIESTA” code. While studied “non-equilibrium Green’s function” (NEGF) method combined with “Landauer-Buttiker” (LB) approach. explored along both armchair (AC) zi...

Since at the regime of nanometer, quantum confinement effects are observed and wave nature electrons is more dominant. Therefore, classical approach current formulation in mesoelectonics nanoelectronics results inaccuracy as it does not consider effect, which only applicable for bulk electronic device. For accurate modeling simulation nanoelectronics, device atomic-level mechanical models requi...

we describe how to obtain electronic transport properties of disordered graphene, including the tight binding model and nearest neighbor hopping. we present a new method for computing, electronic transport wave function and greens function of the disordered graphene. in this method, based on the small rectangular approximation, break up the potential barriers in to small parts. then using the f...

Emerging trend in semiconductor nanotechnology motivates to design various crystalline nanotubes. The structural and electronic transport properties of single walled zigzag Gallium Arsenide nanotubes have been investigated using Density Functional Theory (DFT) and Non-Equilibrium Green’s Function (NEGF) based First Principle formalisms. Structural stability and enhanced electronic transmission ...

The modeling of nano-electronic devices is a cost-effective approach for optimizing the semiconductor device performance and guiding fabrication technology. In this paper, we present capabilities new flexible multi-scale nano TCAD simulation software called Nano-Electronic Simulation Software (NESS). NESS designed to study charge transport in contemporary novel ultra-scaled devices. order simul...

With the rapidly increasing integration density and power in nanoscale electronic devices, thermal management concerning heat generation energy harvesting becomes quite crucial. Since phonon is major carrier semiconductors, transport due to phonons mesoscopic systems has attracted much attention. In quantum studies, nonequilibrium Green’s function (NEGF) method a versatile powerful tool that be...

BACKGROUND Interspecific hybrid bermudagrass [Cynodon dactylon (L.) Pers. x C. transvaalensis Burtt-Davy] is one of the most widely used grasses on golf courses, with cultivars derived from 'Tifgreen' or 'Tifdwarf' particularly used for putting greens. Many bermudagrass cultivars established for putting greens can be genetically unstable and lead to the occurrence of undesirable off-type grasse...

Injecting spins into nonmagnetic molecular devices has attracted much attention in spintronics. Herein, we propose a novel strategy to introduce magnetism single benzene molecule coupled with two armchair graphene nanoribbons (AGNR) electrodes, where the ends of AGNR electrodes are cut zigzag-edge triangular graphenes (ZTGs). The spin-dependent transport properties junction investigated by usin...
