In this paper, we systematically investigate the synergistic regulation of ultraviolet and mechanical loading on the electromechanical behavior of a GaN nanowire. The distributions of polarization charge, potential, carriers, and electric field in the GaN nanowire are analytically represented by using a one-dimensional model that combines pyro-phototronic and piezo-phototronic properties, and then, the electrical transmission characteristics are analyzed. The results suggest that, due to the pyro-phototronic effect and ultraviolet photoexcited non-equilibrium carriers, the electrical behavior of a nano-Schottky junction can be modulate by ultraviolet light. This provides a new method for the function improvement and performance regulation of intelligent optoelectronic nano-Schottky devices.
在本文中，我们系统地研究了紫外线和机械负载对氮化镓纳米线机电行为的协同调控。通过使用一个结合了热光电子和压光电子特性的一维模型，解析地给出了氮化镓纳米线中极化电荷、电势、载流子和电场的分布，进而分析了电传输特性。结果表明，由于热光电子效应和紫外线光激发的非平衡载流子，纳米肖特基结的电学行为可被紫外线调制。这为智能光电纳米肖特基器件的功能改进和性能调控提供了一种新方法。
