A field-effect transistor includes a channel-forming region composed of an organic compound crystal including &#x3c0;-electron conjugated molecules each containing chalcogen atoms as a constituent, wherein the distance between chalcogen atoms of adjacent &#x3c0;-electron conjugated molecules is short, and the organic compound crystal has a periodic structure in which &#x3c0;-electron conjugated molecules are two-dimensionally or three-dimensionally linked together.

Organic compound crystal and field-effect transistor

A flexible organic single crystal has a plurality of columns. The plurality of columns includes a plurality of planar organic compounds arranged so that molecular planes of molecules are respectively parallel to each other. As the organic compound, an organic compound is used that has a large molecular plane and a large area overlapping on an adjacent organic compound due to an intermolecular interaction. Further, energy changes in proportion to a strain. In this structure, when force along the direction of a stack axis is exerted, an angle formed by the stack axis and the normal of the molecular plane of the organic compound changes. Thus, the single crystal obtains flexibility.

Organic crystal

An organic semiconductor material represented by the following general formula (1): wherein X1 to X4 each independently represent a chalcogen atom; and at least one of R1 and R2 represents a substituent for obtaining solubility, and R1 and R2 may be connected to each other to form a ring.
