Effects of applied lateral electric field and hydrostatic pressure on the intraband optical transitions in a GaAs/Ga1− xAlxAs quantum ring
AK Manaselyan, MG Barseghyan… - Physica E: Low …, 2014 - Elsevier
In this paper the simultaneous effects of applied lateral electric field and hydrostatic pressure
on the intraband linear optical absorption coefficient have been investigated in a two-
dimensional GaAs/Ga 1− x Al x As single quantum ring. The lateral confinement potential of
the ring is approximated by square finite potential well model. The one electron energy
spectrum has been found using the effective mass approximation and an exact
diagonalization technique. We find that for fixed geometric dimensions, the hydrostatic …
