Review of photoresponsive properties at SrTiO3-based heterointerfaces |
(color online) (a) Time evolution of the resistance at Ni doped LAO/STO (x = 0) heterointerfaces under the irradiation of light with a power density of 0.5 W/cm2 at different temperatures. (b)–(d) Temperature dependence of PR values, resistance under the irradiation (0.5 W/cm2), and resistance under the irradiation with different power densities, respectively.[ |
