In this paper, we investigate the effect of strain on silicene nanoribbon by using tight binding model.Using appropriate models for silicene, we apply a variable strain to Silicene nanoribbon and analyzed the impact of strain [...]
We investigate the effect of moisture-chemisorption on the electron transport properties in a (8, 0) semiconducting silicon-carbide nanotube (SiCNT) by applying self consistent non-equilibrium Green’s function formalism in combination with the density-functional theory. The results [...]
In present work we studied Conduction properties of nanoscale contacts DFT/NEGF approach. Such calculations give insight into details behind the conductance that is not readily available in experiments. For example, we may learn how the [...]
In the sub-50nm scale, the aggressive scaling of MOSFETs is expected to culminate in dual-gate (DG) architectures on SOI substrates. DG MOSFETs are widely accepted to be the ultimate design that silicon can deliver in [...]
Within the non-equilibrium Green's function formalism numerical integration plays an important role. Several adaptive integration methods were realized and compared regarding convergency within a self-consistent Schrödinger-Poisson loop, computation time and memory consumption.
We used a first-principle atomistic scale method, based on density functional theory and non-equilibrium Green’s function to study the electron tunneling current through ultra thin silicon oxide films. The Si/SiO2 model interface has been constructed [...]

Electronics based on carbon nanotubes (CNT) has received a lot of attention recently because of its tremendous application potential, such as active components and interconnects in nanochips, nanoelectromechanical systems (NEMS), display devices, and chemical and [...]
