Transient Characteristics of Photoluminescence from GaAs/Ga0.7Al0.3As Single Quantum Well Structure

Abstract
Transient characteristics of luminescence from single quantum well (SQW) structure have been examined using a time-correlated single photon counting method. The decay time of the SQW luminescence is shorter than that of bulk sample. The rapid decay is considered to reflect the enhancement of recombination due to localization of excitons. The disagreement between the present results and those reported by other researchers is discussed.
