... lmost independent of the excitation power which is a typical feature of the type-I band transition. Therefore, the interband transition of the GaSb QD would be the only proper origin of the high- energy ... and InAs/GaSb [16,17]. The reason is that they offer compara- tively large bandgap energies and provide a possibility of covering the whole middle and far-infared optical r...
