Hole spin dynamics in constant and alternating electric fields

摘要

Intercollisional dynamics of hole spin, when free holes are subjected to an external electric field, is considered. Coherent evolution of spin projections and the population in valence bands is presented for dc and harmonic fields. Spin operators in the band representation are found and it is shown that there appears an uncertainty related with band degeneracy. The results obtained may be useful in the simulation of simultaneous spin and charge transport in p-type semiconductors, for example, by the Monte Carlo method.
