The role of surface charge field in two-beam coupling in liquid crystal cells with photoconducting polymer layers
In liquid crystal cells with photoconductive poly(N-vinlyl carbazole) polymer layers, an external dc field can be completely screened by surface charge layers that develop at the liquid crystal-polymer interface. Under spatially modulated illumination, surface charge layers can be discharged in brig...
