Luminescence Peculiarities on (Alga)as Single Quantum-Well

This paper reports on single quantum well characterization by means of luminescence excited with a laser (photoluminescence) and an electron beam (cathodoluminescence) at liquid helium temperatures. Small quantum well regions with smaller confinement were observed. They seem to be associated with dislocations originated at the substrate. The observed shift of the X (e-hh) peak position versus the excitation level can be explained by luminescence generation in different lateral regions of the quantum well.
