论文摘要
研究了绿色和紫外线激光对Ba $ _ {0.8} $ sr $ _ {0.2} $ tio $ _3 $ _3 $/lamno $ _3 $异构结构电阻的影响。在80-200 k范围的照明中，在稳态值的〜15％下诱导瞬态电阻成分，与瞬态分量相关的时间常数为〜12 s。阴性光抗效应在绿色，红外和紫外线照明下发现。
The effect of green and ultraviolet laser light on Ba$_{0.8}$Sr$_{0.2}$TiO$_3$/LaMnO$_3$ heterostructure electrical resistance was studied. In 80-200 K range illumination induces transient resistance component at ~15% of the steady-state value, the time constant associated with the transient component is ~12 s. The negative photoresistance effect is found under green, infrared and ultraviolet illumination.
