Photovoltaic Characteristic of La0.7Sr0.3MnO3/ZnO p-n Heterojunction
-
Abstract
We report on the photovoltaic properties of La0.7Sr0.3MnO3/ZnO heterojunction fabricated by pulsed laser deposition methods. Nanosecond
photovoltaic pulses are observed in this junction in the wavelength range from ultraviolet--visible to infrared. A qualitative explanation is presented, based on an analysis of the photovoltaic signals of p-n heterojunction. -
