Abstract
An organic transistor includes a semiconductor section that includes a thin-film laminate in which a first organic thin film and a second organic thin film are alternately stacked. The thin-film laminate includes at least two layers of the first organic thin film. The first organic thin film is a pentacene thin film, and the second organic thin film is an amorphous organic thin film. The pentacene thin film may be a pentacene bilayer thin film, and the amorphous organic thin film may be a tetraaryldiamine thin film. The tetraaryldiamine thin film may be an α-NPD thin film. The organic transistor has improved transistor characteristics (e.g., mobility, ON/OFF ratio, or threshold value control).
