Abstract:
1. An organic FET comprising: a substrate; a gate insulating film disposed on the substrate; a metal source electrode and a metal drain electrode disposed on the gate insulating film in such a manner that they face each other in a horizontal direction; and an organic semiconductor layer covering the gate insulating film, the source electrode and the drain electrode; (1) a first organic molecule layer being formed between the top surface of the source electrode and the semiconductor layer, and between the top surface of the drain electrode and the semiconductor layer; (2) a second organic molecule layer being formed between the opposing side surfaces of the source electrode and the semiconductor layer, and between the opposing side surfaces of the drain electrode and the semiconductor layer; (3) the first organic molecule layer consisting of an alkanethiol molecule that has a carbon number of at least 4 and that may have at least one substituent; and (4) the second organic molecule layer consisting of at least one-type of molecule selected from the group consisting of p-thiocresol molecules and thiophenol molecules.
