Organic compound crystal and field-effect transistor

摘要

A field-effect transistor includes a channel-forming region composed of an organic compound crystal including pi-electron conjugated molecules each containing chalcogen atoms as a constituent, wherein the distance between chalcogen atoms of adjacent pi-electron conjugated molecules is short, and the organic compound crystal has a periodic structure in which pi-electron conjugated molecules are two-dimensionally or three-dimensionally linked together.
