Ks. Zhuravlev et al., EFFECT OF SURFACE ACOUSTIC-WAVES ON LOW-TEMPERATURE PHOTOLUMINESCENCEOF GAAS, Applied physics letters, 70(25), 1997, pp. 3389-3391
The near-band-gap low-temperature photoluminescence (PL) in a pure fil
m of GaAs in the presence of surface acoustic waves (SAW) has been stu
died experimentally. The complex behavior of the PL peak intensities w
ith SAW power in the excitonic and acceptor spectral regions results f
rom a charge bunching due to the piezoelectric field of SAW. (C) 1997
