Abstract

Artificially constructed oxide heterointerfaces have attracted much attention. Herein, the novel all-perovskite p-n heterojunction composed of a colossal magnetoresistive manganite La_0.7Sr_0.3 MnO₃ (LSMO) and an n-type transparent semiconducting BaSnO₃ (BSO) is designed via optimizing the growth condition. This LSMO/BSO p-n junction exhibits good rectification with a forward-to-reverse ratio of 275 at 1 V, high photo detection capability with a photo-to-dark current of 581.9 at -0.5 V, high ultraviolet light sensitivity with a UV (360 nm)-to-visible (532 nm) ratio of ∼2.4 × 10³, and a significantly magneto-tunable photocurrent with a variation ratio of ∼1.25 % under 532 nm illumination and 0.5 T magnetic field. As a result, combining synergistically the functionality of diode and magnetically tunable photo detector, the LSMO/BSO p-n junction is a promising candidate for advanced magneto-optoelectronic devices.
