Abstract
Multiquantum wells (MQW) with a structure of Al x Ga1-x As/Al y Ga1-y As were grown by pulsed molecular beam epitaxy in order to raise the emission energy in MQW of the AlGaAs system. Sharp photoluminescence spectra indicate the high quality of MQW structure and the peak emission energy agreed with the calculated value of n=1 electron and hole transition.
