Abstract

Based on an autonomous monitoring system, we observed localized heating modulates the photocurrent of VI4O12 and Fe5IO7 micro-films. Diffuse reflectance spectroscopy and Raman were used to characterize the samples. A model for explaining the phenomena was derived utilizing localized electric polarization which includes the key factor related to the variation of charge-shifting length. The photocurrent is considered to be in inverse proportion to the charge shifting length.
