摘要:

The near-band-gap low-temperature photoluminescence (PL) in a pure film of GaAs in the presence of surface acoustic waves (SAW) has been studied experimentally. The complex behavior of the PL peak intensities with SAW power in the excitonic and acceptor spectral regions results from a charge bunching due to the piezoelectric field of SAW. ©1997 American Institute of Physics.
