|Title:||Hydrostatic-pressure effects on the correlated electron-hole transition energies in GaAs-Ga1-xAlxAs semiconductor quantum wells|
|Abstract:||The effects of hydrostatic pressure on the correlated e-h transition energies in single GaAs-Ga1-xAlxAs quantum wells are calculated via a variational procedure, in the framework of the effective-mass and nondegenerate parabolic-band approximations. The valence-band anisotropy is included in our theoretical model by using different hole masses in different spatial directions. Both heavy- and light-hole exciton energies are obtained, and correlated e-h transition energies are found in good agreement with available experimental measurements.
