The temperature dependence of the piezotronic and piezophototronic effects in a-axis GaN nanobelts from 77 to 300 K is investigated. The piezotronic effect is enhanced by over 440% under lower temp-eratures. Two independent processes are discovered to form a competing mechanism through the investigation of the temperature dependence of the piezophototronic effect in a-axis GaN nanobelts.
研究了 77 到 300 K 温度范围内 a 轴 GaN 纳米带的压电器件和压光电器件效应的温度依赖性。在较低温度下，压电器件效应增强超过 440%。通过研究 a 轴 GaN 纳米带的压光电器件效应的温度依赖性，发现了两种独立的过程，形成了竞争机制。
