摘要

提出了两种新型紫外敏感iii -氮化物表面声波器件。我们演示了基于Al/sub -x/ Ga/sub - l-x/ n的表面声波延迟线振荡器，它被用作一种能够太阳盲操作的紫外线传感器，可以远程无线采集输出信号。此外，我们还报道了saw诱导的高频电阻调制效应，该效应在紫外线照射下显着增加。

Ultraviolet-sensitive AlGaN-based surface acoustic wave devices

Two types of novel ultraviolet-sensitive III-nitride based surface acoustic wave devices are presented. We demonstrate the Al/sub x/Ga/sub l-x/N-based surface acoustic wave delay-line oscillator, which is applied as an ultraviolet sensor capable of solar-blind operation with remote wireless pickup of the output signal. Also, we report on the SAW-induced high-frequency resistance modulation effect, which is dramatically increased under ultraviolet illumination.
