A non-equilibrium Green function formalism (NEGF) is used to study the conductance of a side-gated quantum point contact (QPC) in the presence of lateral spin-orbit coupling (LSOC). A small difference of bias voltage between the two side gates (SGs) leads to an inversion asymmetry in the LSOC between opposite edges of the channel. This triggers a spontaneous spin polarization, which is signific...

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...

in this study a simple and general chemical association theory is introduced. the concept of infinite equilibrium model is re-examined and true mole fractions of associated species are calculated. the theory is applied to derive the distribution function of associated species. as a severe test the application of presented theory to the van der waals mixture model is introduced in order to perfo...

We propose a coupling scheme, where the advantages of the coherent Green’s function formalism are combined with the ability of the Wigner formalism to account for phasebreaking processes of interaction with phonons and other lattice imperfections. The Green’s function formalism is used to calculate the coherent Wigner function which provides the initial condition in an equation, from which corr...

In this paper we present a general theory for an arbitrary 2D channel with "spin momentum locking" due to spin-orbit coupling. It is based on a semiclassical model that classifies all the channel electronic states into four groups based on the sign of the z-component of the spin (up (U), down (D)) and the sign of the x-component of the velocity (+, -). This could be viewed as an extension of th...

We propose a new Metal-oxide-semiconductor carbon-nanotube transistor (MOSCNT) in which source (S) and drain (D) regions are formed by band engineered multi-wall carbon nanotubes (BE-MWCNTs). The gradual potential profiles of these band-engineered S/D regions weakening the longitudinal confinements in the channel reduce the band-to-band tunneling significantly and hence eliminating the ambipola...
