摘要：
Organic thin film transistors (TFTs) have been fabricated using thermally evaporated films of the oligophenyls p-quaterphenyl (p-4P), p-quinquephenyl (p-5P), and p-sexiphenyl (p-6P). The field-effect mobility of these TFTs ranges from 10(-2) cm(2)/V s for p-4P to 10(-1) cm(-2)/V s for p-6P with on/off current ratio from 10(5) to 10(6). These values are comparable to those achieved using the more widely studied organic semiconductors alpha-sexithienyl (alpha-6T) and pentacene. X-ray diffraction reveals a high degree of molecular ordering, believed to be important for obtaining high field-effect mobility in organic TFTs. (C) 1997 American Institute of Physics.
