Fabrication and field effect transistor characteristics of well-ordered pentacene film
Pentacene was vapor-deposited on the NaCl substrate and friction-transferred PTFE layer. Pentacene molecules crystallized in bulk phase and/or thin film phase depending on the deposition condition. The polarized absorption spectra of pentacene/PTFE double layer showed an anisotropic feature. Pentacene oriented uniaxially taking edge-on state an a PTFE layer. The electrical property of pentacene/PTFE double layer also indicated anisotropic feature. The field effect mobility along to the traverse of the friction direction was 4.2 x 10(-1) cm(2)/Vs.
