Elementary Electronic Excitation from a Two-Dimensional Hole Gas in the Presence of Spin-Orbit Interaction

Xu, Wen; Lin, L B


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) interaction induced by the Rashba effect, The calculation is carried out using a standard random-phase-approximation approach. It is found that, in such a spintronic system, plasmon excitation can be achieved via intra- and inter-SO electronic transitions around the Fermi level. As a result, the intra- and inter-SO plasmon...[Show more]
