摘要：

We study piezoelectric field effects in the ultimate atomic limit. The insertion of piezoelectrically active (211)-InAs lattice planes in GaAs gives rise to optical phenomena not observed in analogous (100) structures. The InAs-related luminescence exhibits a pronounced blue shift with increasing excitation density. The nonlinear dependence of the corresponding luminescence efficiency is a manifestation of the internal piezoelectric field in the strained InAs sheets.
