Non-equilibrium Green's function study of transport in disordered double-layer graphene systems
… graphene systems are investigated using the non-equilibrium Green's function (NEGF) formalism. The complexity of such a structure makes it imperative to study the effects of lattice vacancies which will inevitably arise during fabrication. Room-temperature performance characteristics for both …

Computational study of graphene nanopore sensor for DNA sensing
… Poisson-Boltzmann formal- ism with Non-Equilibrium Green's Function (NEGF) technique along with charge densities of DNA arising from MD simulations to show detection of rotational and positional conformation of a double-stranded DNA (dsDNA), inside the nanopore, via sheet currents in …

Modeling of photocurrent spectra induced by nonlinear absorption in high-indium-content iii-nitride disk-in-wire photodiode
… the superlattice region in the TI-QCL by using non-equilibrium Green's function (NEGF). As for the quantum disk-in-wire photodiode, we developed a band structure calculation method based on an effective bond-orbital model (EBOM). The model is incorporated with the transport model to investigate …

Electron-phonon interactions in double layer graphene superfluids
… consider the scattering of charge carriers by phonons in each of the constituent graphene monolayers. We use the non- equilibrium Green’s function (NEGF) formalism to examine the effect that carrier-phonon scattering has on transport in such a device. The simulations show that the effect of …

Atomistic and mesoscopic simulations of heat transfer across heterogeneous material interfaces
… techniques that enable spectrally-resolved phonon transport measurements at the nanoscale along with the development of high-fidelity simulation methods have provided a renewed interest in the fundamental physics of heat transfer across interfaces. Miniaturized electronic devices and …

AB initio study and design of 2D materials/III-nitrides-based post-CMOS devices using first-principles multiphysics simulation framework
… multiphysics framework coupling density functional theory (DFT) and non-equilibrium Green's function (NEGF) method. To start with, we provide a systematic and theoretical DFT study of the electronic properties of a large number of impurities, vacancies, and adatoms in monolayer MoS2, …
