作为一种高灵敏度的光开关，研究了LaSrAlO 4单晶的增强型光致可逆开关。LaSrAlO 4晶体在偏压Vb= 30 V时具有较高的开关比，开关比为66。在−30- 30 V范围内，获得了开/关比与偏置电压的线性关系，没有任何饱和趋势。与其他复杂的方法相比，电场可调机制是提高光电性能最简单、最直接的途径。
An enhanced photoinduced reversible switching of LaSrAlO4single crystal was investigated as a highly sensitive photoswitch. The LaSrAlO4crystal showed an enhanced reversible photoswitching performance with high on/off ratio of 66 at bias voltage Vb=30V. A linear relationship was obtained to the on/off ratio as a function of bias voltage without any saturation trend from −30–30V. Compared with other complicated methods, the mechanism of electric field tunable would be the simplest and possibly the most direct way to develop the optoelectronic performances.
