Abstract

The optical properties of a semiconductor can be modulated through both deformation potential effects and through the electric field. Piezoelectrically active surface acoustic waves (SAW) which are accompanied by both mechanical strains and electric fields can be used to modulate optical properties of a semiconductor. Moreover, with the development of advanced semiconductor techniques, it is possible to fabricate multiple quantum well (MQW) structures which offer the advantage, compared with bulk semiconductors, of strong exciton absorption stable at room temperature. The common crystal orientation of GaAs for the SAW-based applications has been the (100)-cut, [011]-propagation direction. We here investigate acoustic properties of new GaAs-cuts (n11), n = 1, 2, 3 and 4.
