By using the tight-binding model and non-equilibrium Green's function method (NEGF), we study band structures transport properties of a silicene nanoribbon with line defect where bulk energy gap is opened due to sublattice symmetry breaking. The flat subband bends downwards or upwards effect defect. spin-orbit coupling induces quantum spin Hall states. Especially, depends on distance between ed...

The understanding and modeling of inelastic scattering thermal phonons at a solid/solid interface remain an open question. We present fully quantum theoretical scheme to quantify the effect anharmonic phonon-phonon via nonequilibrium Green's function (NEGF) formalism. Based on real-space rate matrix, decomposition interfacial spectral energy exchange is made into contributions from local nonloc...

for an Invited Paper for the MAR06 Meeting of The American Physical Society Conductance Through Single Organometallic Molecules1 HAROLD U. BARANGER, Duke University We have undertaken ab initio calculations of the conductance and I-V curve of a variety of single molecules bridging two metallic leads. The method adopted is a non-equilibrium Green function (NEGF) approach to transport combined wi...

Multiple foodborne illness outbreaks have been associated with the consumption of fresh produce. Investigations have indicated that microbial contamination throughout the farm-to-fork continuum often contributed to these outbreaks. Researchers have hypothesized that handling practices for leafy greens in restaurants may support contamination by and proliferation and amplification of pathogens t...

A data processing scheme is proposed to deconvolve the recording footprint noise in the migration image. For computational convenience, we assume a far eld approximation and shift invariance in the Greens function. Preliminary results with synthetic data show that the footprint signature can be partially suppressed by deconvolution with the migration Greens function. However, much work needs to...

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 ...

Asymmetric I /V curves with respect to the polarity of the voltage bias were observed in the Hg /Au junctions containing bilayers of alkanethiols of different chain length. A larger current resulted when a negative bias was applied to the metal carrying a longer chain alkanethiol monolayer. This behavior is simulated using a single molecule junction model, within the frameworks of the extended ...

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...
