Abstract
The structural and optical properties of multiquantum‐well (MQW)structuresgrown by molecular beam epitaxy are strongly dependent on the substrate temperature T s during the growth. A study of the optimization of MQWstructures as a function of T s is carried out using optical and electron microscopy and photoluminescence characterization. Optimal temperatures in the range 670–730 °C are shown to yield smooth free surfaces and interfaces and high quantum efficiencies.Keywords
