Abstract:
Using micro-photoluminescence, emissions from single CdSe quantum dots were observed from the cleaved (110) facets of ZnSe/CdSe/ZnSe heterostructures grown on GaAs (001) substrates. The emission intensity of a single quantum dot was linearly proportional to the excitation intensity, demonstrating excitonic features. Emissions from these single quantum dots were found to polarize within the (001) plane, providing information on the shapes of the quantum dots.Keywords: SINGLE CDSE QUANTUM DOTS; MICRO-PHOTOLUMINESCENCE; ZNSE/CDSE/ZNSE HETEROSTRUCTURES; MOLECULAR BEAM EPITAXY
