Abstract

A response time as short as 5.4 ms and an exponential gain coefficient as large as $1795.0{\mathrm{cm}}^{-1}$ were obtained in ${\mathrm{C}}_{60}$ doped 4,$4^{\prime }\text{-}n$-pentylcyanobiphenyl liquid crystal cells sandwiched with two indium tin oxide glass plates coated with nanoscale photoconductive ZnSe films, which is believed to be facilitating charge-carrier generation and transportation and, hence, to be responsible for the fast response rate. The surface-mediated photorefractive effect and the ZnSe interlayers were both behind the high gain coefficients. The two-dimensional diffraction patterns observed in our system are also discussed.
