Title: GAMMA-TO-X(Z) ELECTRON-TRANSFER TIMES IN TYPE-II SUPERLATTICES DUE TO EMISSION OF CONFINED PHONONS
Author: DEPAULA, AM
WEBER, G
Abstract: We calculate the GAMMA --> X(z) electron transfer times due to the emission of confined longitudinal optical phonons in type-II GaAs-AlAs and AlGaAs-AlAs superlattices. A dielectric continuum model is employed to describe the electron-confined-phonon interaction and the electron envelope wave functions are obtained from a Kronig-Penney model. The calculated transfer times compare within order of magnitude, or better, with available experimental results and we obtain a good qualitative description of the transfer time dependence on the layer thicknesses.
