Abstract

We report here the effect of the photoelectrochemical photocurrent switching (PEPS) observed on highly-ordered pristine anodized Ti/TiO for the first time. At negative potential bias, blue irradiation gives cathodic photocurrent, whereas anodic photocurrent was observed for ultraviolet irradiation. We believe this phenomenon is due to the electron pathway provided by Ti defect states.

摘要

我们首次在此报告了在高度有序的原始阳极氧化钛/二氧化钛上观察到的光电化学光电流切换（PEPS）效应。在负电位偏压下，蓝光照射产生阴极光电流，而紫外光照射则观察到阳极光电流。我们认为这种现象是由于钛缺陷态提供的电子通道所致。
