COMPARISON OF OPTICAL-PROPERTIES OF CDTE CDMNTE QUANTUM-WELLS GROWN BY MOLECULAR-BEAM AND ATOMIC LAYER EPITAXY/

Optical properties of a series of CdTe/CdMnTe multi quantum well struc tures grown with MBE and ALE (CdTe quantum wells only) methods are com pared. Based on the results of the photoluminescence experiments we co nclude that the ALE growth leads to a different lateral scale of quant um well width fluctuations, which results in different exciton propert ies in two multi quantum well systems studied. In the wells grown with ALE method excitons are less localized. They can migrate in a quantum well plane between quantum well regions varying in thickness by 1 mon olayer.
