Abstract

Emission peaks of epitaxially lifted off GaAs/AlGaAs multiple quantum wells (MQW) of different well widths were observed to be shifted towards lower energies (redshifted) via temperature dependent photoluminescence spectroscopy due to strain. MQW samples were grown using molecular beam epitaxy and were epitaxially lifted off and bonded to MgO and Si substrates. At T=300K, emission peaks of the epitaxially lifted-off samples were redshifted indicating the presence of residual strain.
