Photoenhanced currents in insulators with various energetic trap distributions

摘要

It was shown that the photocurrent - voltage characteristic does not depend on the type of the trap distribution. However, die current - light intensity characteristic for the monoenergetic trap distribution is linear, for the exponential one is the solid slope and, for the Gaussian one, has different slopes for different light intensity.rnAnalysis of the experimental and numerical results shows that the photoenhanced current can be determined by the Gaussian trap distribution in some anthracene crystals.
