PATTERN FORMATION AND QUASICRYSTAL STRUTURE IN AZOBENZENE POLYMER FILM
有机聚合物薄膜中的横向效应与准晶结构

Pattern formation and transverse effect are reported for azobenzene polymer film.We show,through scanning electron microscopy and polarizing optical microscopy investigation of azobenzene polymer film after being irradiated by degenerate four-wave mixing,that many peak-like islands of azobenzene polymer molecules array in some patterns.Experimental evidence that it is possible to control the photoinduced micro-patterns of the nonlinear organic film via adequately polarized write beams and appropriate power of the write beams,thus making easy growth of nanostructures crystals in azobenzene polymer film.
