Abstract

We studied crystalline analysis on recently developed crystalline films grown from a solution in an oriented way on a substrate. The film is characterized as very high mobility values reaching 5 cm2/Vs for devices with solution-crystallized 2,7-diocthylbenzoselenopheno[3,2-b] benzoselenophene (C8-BTBT) thin films. High-power transmission X-ray scattering is employed to examine the crystallinity of the films, to identify whether or not me structure is same as the bulk structure, and determine the direction of me orientational crystal growth.
