Abstract

The effects of growth temperature on the optical properties of InAs/InGaAs/GaAs quantum dot (QD) structure were investigated at the important temperature range of 25degC to 80degC. Results from QD samples grown at low growth temperature of 450degC suggest better thermal stability as compared to that grown at 510degC. This work suggests the feasibility of obtaining better thermal stability at a low growth temperature for InAs/InGaAs/GaAs QD structures.
