Surface structure relaxation of organic semiconductors affects the properties of organic devices, although such relaxation has not been well explored. Only two examples have been experimentally reported; tetracene shows a large surface relaxation, while rubrene exhibits no relaxation. Therefore, a systematic investigation of the surface relaxation is conducted on [ n]phenacenes ( n = 5, 7, and 9). Electron density analyses are performed based on the synchrotron surface X-ray scattering with the aid of first-principles calculations. The results show little surface relaxation in [ n]phenacenes.

有机半导体[n]非苯单晶的表面结构

有机半导体的表面结构弛豫会影响有机器件的性能,尽管这种弛豫还没有得到很好的探索。只有两个例子被实验报告过;并四苯表现出较大的表面弛豫,而红荧烯则没有表现出弛豫。因此,对 [ n] 非苯 (n = 5、7 和 9) 进行了表面弛豫的系统研究。借助第一性原理计算,基于同步加速器表面 X 射线散射进行电子密度分析。结果表明 [n] 非苯中的表面弛豫很小。
