Elementary electronic excitation from a two-dimensional hole gas in the presence of spin-orbit interaction
W. Xu, L. B. Lin
We present a theoretical study of the elementary electronic excitation associated with plasmon modes in a two-dimensional hole gas (2DHG) in the presence of spin-orbit (SO) interac…

Binding energies of hydrogen-like impurities in a semiconductor in intense terahertz laser fields
J. L. Nie, W. Xu, L. B. Lin
A detailed theoretical study is presented for the influence of linearly polarised intense terahertz (THz) laser radiation on energy states of hydrogen-like impurities in semiconduc…

Coupled plasmon-phonon modes in a two-dimensional electron gas in the presence of Rashba effect
W. Xu, M. P. Das, L. B. Lin
Elementary electronic excitation is studied theoretically for a 2DEG in the presence of spin orbit (SO) interaction induced by Rashba effect. In such a system, coupled plasmon-phon…
