Abstract Electron propagation in a trapped state between an insulator and a metal during very close contact in a triboelectric nanogenerator (TENG) system was considered in this study. A single energy level (E0) was assumed for the trap and wave function inside the trap, which is related to the ground state energy. The phase of the waveform in the metal (neglecting the rebound effect at the wall) was assumed very small (δ′ ≪ 1) because of the large size of the metal. The contact distance between the trap and metal is very small, which allows us to ignore the vacuum potential. Based on our results, the probability of finding an electron inside the trap as a function of time was found to be in oscillation (i.e., back-and-forth propagation of the electron between the trap and metal leads to an equilibrium state). These results can be used to understand the quantum mechanisms of continuous contact, particularly in sliding-mode TENG systems.

紧密接触TENG系统陷阱中的电荷分布模型

摘要 本研究考虑了在摩擦纳米发电机 (TENG) 系统中非常紧密接触期间绝缘体和金属之间处于俘获状态的电子传播。陷阱内的陷阱和波函数假定为单一能级 (E0),这与基态能量有关。由于金属的大尺寸,金属中波形的相位(忽略壁处的回弹效应)被假定为非常小(δ' ≪ 1)。陷阱与金属之间的接触距离非常小,这让我们可以忽略真空势。根据我们的结果,发现作为时间函数的陷阱内发现电子的概率处于振荡状态(即,电子在陷阱和金属之间的来回传播导致平衡状态)。
