摘要：
Electrooptic properties of liquid crystal cells with semiconductor substrate are studied. A DC electric field has been applied along the semiconductor substrate. It is shown, that presence of such field results both in reduction of Freedericksz threshold and in essential reduction of characteristic reorientation and relaxation times. For more understanding of the mechanism of current flow through the liquid crystal - semiconductor interface, the Volt-Ampere (V-I) and spectral characteristics of photocurrent for such system have been investigated.
