Abstract :
Self-assembled quantum dots have been grown in the InP/GaInP material system on GaAs substrates. The different types of dots, differentiated by size, exhibit different luminescence features. In particular, peaks at 1.82 eV and 1.57 eV have been observed. Two methods have been utilized to study emission from small regions of the sample: photoluminescence of samples with etched mesas, and cathodoluminescene of samples that have been thinned for electron microscopy. Results from both methods are discussed
