Abstract
The dynamic process of photoelectric effects in the La0.9Sr0.1MnO3/SrNb0.01Ti0.99O3 heterostructure is theoretically revealed by solving equations consisting of time dependent drift–diffusion, Richardson thermionic emission current, and Shockley–Read–Hall recombination. The calculated time dependent evolution of photovoltage and the variation of carrier concentration are obtained. Present results indicate that a smaller parallel resistance should result in faster photoelectric response, but reduce the peak value of the photovoltage in a La0.9Sr0.1MnO3/SrNb0.01Ti0.99O3 heterojunction. In addition, the increase of the carrier mobilities induced by applying higher energy photons can decrease the rise time but increase the peak value of the photovoltage.
