摘要

LiNbO3中的光致电荷输运是由类铁杂质的存在定义的，Fe2+是供体，Fe3+是电子的受体。双能级方案给出了光电导率(即光折射逆响应的2倍)和光强度的线性依赖关系2。

Photoinduced Charge Transport in Optical Damage Resistant LiNbO3:Me (Me = Mg, Zn)

Photoinduced charge transport in LiNbO3 is defined by presence of a Fe-like impurity, Fe2+ being the donor, Fe3+-the acceptor of electrons1. Two level scheme gives the linear dependence of photoconductivity (that is of inverse response 2 times of photorefraction) on the light intensity2.
