It has long been puzzling regarding the physical origin of the thermally induced red-shift of Raman optical phonons in group III nitride crystals despite some possible mechanisms such as phonon decay, thermal expansion, interfacial effects, or their

A general approach is presented for calculating the dynamic conductance of coupled quantum dot systems. To consider the long-range Coulomb interaction, we introduce the capacitances between the leads and dots, gate electrodes and dots, and dots and d

This work deals with the electronic transport in a system of an arbitrary number of quantum dots connected in series by tunnel coupling. We calculate the “lesser” and retarded Green's functions based on the nonequilibrium Green's function formali

Motivated by applications of second-order nonlinear capacitances in semiconductor measurements of charge carrier densities, we investigate the profound relationship between the second-order nonlinear emittance and the total and partial local densitie

General formulae for calculating the ac current response to time-dependent bias for Anderson impurity model are presented basing on the nonequilibrium Green function. To calculate the lesser Green function in the limit U→∞, we have combined the K

Photonic band structures explored in the past 12 years were mainly fabricated from dielectric materials, typically used in the semiconductor technology. However, we foresee novel applications and interesting possibilities by incorporating the photoni

In this investigation, we study the combined effects of a parabolic potential and a Coulomb impurity on the cyclotron resonance of a three-dimensional bound magnetopolaron, under the condition of strong parabolic potential. We only consider the case

We investigated the cyclotron resonance of a three-dimensional bound magnetopolaron, in the presence of a strong parabolic potential and weak electron-LO-phonon coupling. The polaron resonances in a low-lying energy level are studied and the correspo

The longitudinal resistances of a six-terminal graphene $p\text{\ensuremath{-}}n$ junction under a perpendicular magnetic field are investigated. Because of the chirality of the Hall edge states, the longitudinal resistances on top and bottom edges o
