Abstract

Abstract: A novel complex thin film has been prepared by vacuum coevaporation of 1, 4-bis(-1,1-dicyanoviny1)benzene (BDCB) and C₆₀ . Surface morphology and structure of the complex BDCB-C₆₀ thin film are considerably different fromthose of both BDCB and C₆₀ film, as revealed by high resolution scanningelectron microscopy and X-ray diffraction. Sandwiched device Ag/BDCB-C₆₀/Ag has shown electrical field-controlled bistable electronic switching and memorybehaviors.

Key words: C₆₀, elctrical switching, scanning electron microscopy, X-ray diffraction

摘要： 利用真空双源同时蒸发法制备了新型C₆₀-1,4-b is(-1,1-dicyanovinyl) benzene(BDCB)复合薄膜。用高分辨扫描电镜和X-射线衍射仪分析了BDCB-C₆₀复合薄膜的表面形貌和结构特性，结果表明BDCB-C₆₀复合薄膜是一种不同于纯C₆₀薄膜和纯BDCB薄膜的结构相。Ag/BDCB-C₆₀/Ag的三明治型结构具有电学双稳态现象和记忆特性。
