查询词典 Al

Simply inferred the optical-rectification effect in the silicon, discovered the optical electric voltage aeolotropic rule through the experiment of observing the relation between the optical electric voltage and the light wave direction of polarization and the orientation of crystal changing when the Si/Al schottky barrier has been illuminated, and confirm the reason is that the existence of self-field destroy the crystal symmetry, produce second-order nonlinear optical-rectification effect, and the direct-current field which has been produced by the optical-rectification effect and the self-field affect mutually.

推导了硅中的光整流效应，并通过观测Si/Al肖特基势垒受光照时产生的光生电压与光波偏振方向和晶向的变化关系的实验，发现了光生电压的各向异性规律，并确定这是由于内建电场的存在使晶体对称性被破坏，产生二阶非线性效应的光整流，光整流产生的直流电场又与内建电场相互作用的结果。
