These results , which are not intuitively explained by electrostatics arguments , have been obtained by combining in situ real time structural and electrical characterization together with ex situ AFM measurements , on thin films of a relevant n - type organic semiconductor , N , N ' - bis ( n - octyl ) - dicyanoperylene - 3 , 4 : 9 , 10 - bis dicarboximide grown by sublimation in a quasi - layer - by - layer mode at different substrate temperatures .
 Chemical: N , N ' - bis ( n - octyl ) - dicyanoperylene - 3 , 4 : 9 , 10 - bis dicarboximide
