A charge transfer single crystal field effect transistor operating at low voltages

摘要

An organic FET employing a single crystal of a donor-acceptor system based on coronene tetracarboxylate and a methyl viologen derivative exhibited an impressive mobility of 0.53 cm~2 V~(-1) s~(-1), operating under 2 V in the ambient atmosphere. Quantum mechanical calculations have provided an insight into the hole-dominant transport in the crystal.
