Electroluminescence emission controlled by means of surface acoustic waves (SAWs) in planar light-emitting diodes (pLEDs) is demonstrated. Interdigital transducers for SAW generation were integrated onto pLEDs fabricated following the scheme which we have recently developed [Cecchini et al., Appl. Phys. Lett. 82, 636 (2003)]. Current-voltage, light-voltage, and photoluminescence characteristics are presented at cryogenic temperatures. We argue that this scheme represents a valuable building… 
Surface acoustic wave-induced electroluminescence intensity oscillation in planar light-emitting devices

An experimental investigation of the direct current induced by transmitting a surface acoustic wave (SAW) through a quasi-one-dimensional (1D) channel defined in a GaAs - AlGaAs heterostructure by a split gate finds that at low SAW power levels the current reveals oscillatory behaviour as a function of the gate voltage with maxima between the plateaux of quantized 1D conductance.
