The monolayer crystal phase structure of the organic semiconductor 7-decyl-2-phenyl[1]benzothieno[3,2-b][1]benzothiophene was reinvestigated. A smaller two- or three-step bilayer-monolayer transition model than the previous transition model was newly proposed. The carrier mobilities of the resultant two monolayer crystal structure models were theoretically compared. The results show that the antiparallel monolayer crystal model that can be transformed with only two steps (without any rotation) from the bilayer structure is more probable than the nanosegregated model.

有机半导体 7-癸基-2-苯基[1]苯并噻吩并[3,2-b][1]苯并噻吩的单层晶体结构，重新审视

重新研究了有机半导体7-癸基-2-苯基[1]苯并噻吩并[3,2-b][1]苯并噻吩的单层晶相结构。新提出了比以前的过渡模型更小的两步或三步双层-单层过渡模型。从理论上比较了所得两种单层晶体结构模型的载流子迁移率。结果表明，从双层结构仅通过两个步骤（没有任何旋转）就可以转换的反平行单层晶体模型比纳米隔离模型更有可能。
