摘要：
Electroluminescence emission from surface acoustic wave-driven light-emitting diodes (SAWLEDs) is studied by means of time-resolved techniques. We show that the intensity of the SAW-induced electroluminescence is modulated at the SAW frequency (similar to 1 GHz), demonstrating electron injection into the p-type region synchronous with the SAW wave fronts.
