Surface-acoustic-wave driven planar light-emitting device

摘要

Electroluminescence emission controlled by means of surface acoustic waves(SAWs) in planar light-emitting diodes (pLEDs) is demonstrated. Interdigitaltransducers for SAW generation were integrated onto pLEDs fabricated followingthe scheme which we have recently developed. Current-voltage, light-voltage andphotoluminescence characteristics are presented at cryogenic temperatures. Weargue that this scheme represents a valuable building block for advancedoptoelectronic architectures.
