摘要

Optical and structural properties of multilayer structures with InAs/GaAs quantum dots are investigated. It is shown that under optimal growth conditions, 1.3-1.4 #mu#m emission can be achieved. Possible scenarios of quantum dot behaviour evaluation are discussed in a frame of elastic theory to explain differences in optical properties of the grown structures.
