Abstract

Contact electrification (CE) is a physical phenomenon that occurs between two materials. When two materials with different electron affinity are contacted, electrons move along the contacting surfaces due to triboelectrification. The result of this effect is direct current. In this study, the triboelectric current is generated by the bindington energy generated by sliding a water drop on n-type, p-type and GaAs p-n junction. In addition, since the water drop is transparent, it is illuminated with 100 mW/cm2 while sliding and tribovoltaic and photovoltaic effects are evaluated together. The fact that the current value obtained was in the order of microampere (μA) showed that GaAs can be used in triboelectric nanogenerators (TENGs).

研究砷化镓半导体-液体界面的光伏效应和摩擦光伏效应
接触电化(CE)是发生在两种材料之间的一种物理现象。当两种具有不同电子亲和力的材料接触时,由于三电化作用,电子会沿着接触表面移动。这种效应的结果就是直流电。在本研究中,三电化电流是由水滴在 n 型、p 型和 GaAs p-n 结上滑动产生的结合能产生的。此外,由于水滴是透明的,因此在滑动的同时以 100 mW/cm2 的功率照射水滴,并同时评估三电效应和光电效应。所获得的电流值在微安(μA)数量级,这表明砷化镓可用于三电纳米发电机(TENGs)。
