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