Abstract :
The authors report the first epitaxial regrowth on lifted-off large-area micron-thick single-crystal GaAs films bonded by surface tension (van der Waals) forces to a foreign substrate. GaAs quantum wells grown by MOCVD on a GaAs film which had been van der Waals bonded to an Si substrate showed linewidths and luminescence efficiencies comparable to those grown directly on GaAs substrates.<>
