Abstract

Pentacene-based organic thin-film transistors (TFT's) with field-effect mobility as large as 0.7 cm2/V·s and on/off current ratio larger than 108 have been fabricated. Pentacene films deposited by evaporation at elevated temperature at low-to-moderate deposition rates have a high degree of molecular ordering with micrometer-sized and larger dendritic grains. Such films yield TFT's with large mobility. Films deposited at low temperature or by flash evaporation have small grains and poor molecular ordering and yield TFT's with low mobility.
