Nearly perfect pentacene single crystals with wide terraces several micrometers in width were grown by crystallization from a pentacene-containing trichlorobenzene solution. Organic field-effect transistors (OFETs) were fabricated with the pentacene single crystals and characterized for their electrical properties. The field effect mobility was found to be in the range of 0.4-0.6 cm(2)/V x s, which is comparable to that of OFETs fabricated with pentacene single crystals prepared by a physical vapor-phase growth method. The results described in this paper clearly demonstrate that the crystallization of organic semiconductors from solution is a promising chemical method for device processing of OFETs.
通过从含并五苯的三氯苯溶液中结晶生长出了具有几微米宽的宽阔平台的近乎完美的并五苯单晶。用这些并五苯单晶制造了有机场效应晶体管（OFET），并对其电学性质进行了表征。发现场效应迁移率在0.4 - 0.6 cm²/V·s范围内，这与通过物理气相生长法制备的并五苯单晶制造的OFET相当。本文所述结果清楚地表明，从溶液中结晶有机半导体是一种用于OFET器件加工的有前景的化学方法。
