Abstract

With the aim of investigating the effect of alkyl chain orientation of self-assembled monolayers (SAMs) on the pentacene growth mode and the performances of organic thin-film transistors (OTFT), pentacene films were deposited on octadecyltrichlorosilane (ODTS) with different alkyl chain orientation. The alky chain orientation of ODTS was controlled by adjusting the reaction temperature. Pentacene films on ordered ODTS were found to have higher crystallinity and better device performances than those on the disordered ODTS, and their differences increased with the substrate temperature. These results can be explained by (1) lattice matching effect between the pentacene crystals and ODTS, and (2) temperature-dependent alkyl chains mobility of ODTS.
