Abstract
The thermal population in photocarrier systems coupled by hole mixing tunneling is studied by an analysis of the high energy tails in cw photoluminescence spectra of asymmetric coupled double wells. Photocarriers in wide well are heated due to hole transfer from the narrow well through resonant tunneling as well as by photon heating. The influences of the excitation intensity and lattice temperature on the tunneling transfer and thermal population are discussed.
