Abstract
Using deep level transient spectroscopy (DLTS), we have studied a GaAs/GaInAs/GaAs single quantum well. The DLTS spectra exhibit both a peak and a plateau: the peak is associated with the thermionic emission of electrons and the plateau corresponds to a quasiconstant emission rate associated with a tunneling emission of electrons from the well towards the conduction band. A modelization of the tunneling effect is proposed, based on Oppenheimer’s approach as to the WKB approximation.Keywords
