Abstract:
1. A field-effect transistor comprising: a single-crystal diamond thin-film; a hole or electron channel formed inside said single-crystal diamond thin-film; and a drain electrode, a gate electrode and a source electrode each formed on a top surface of said single-crystal diamond thin-film, the source, gate, and drain electrodes extending in a longitudinal direction that is parallel to the top surface of said single-crystal diamond thin-film; wherein a [001] direction of the crystal axis of said single-crystal diamond thin-film is inclined with respect to surface orientation of a surface of said single-crystal diamond thin-film, or a [001] direction of the crystal axis of said single-crystal diamond thin-film is inclined with respect to surface orientation of a forming face of said hole or electron channel; and wherein an angle β formed between the longitudinal direction of said source, gate, and drain electrodes and a [110] direction of the crystal axis of said single-crystal diamond thin-film is in the range of from minus 30 degrees to plus 30 degrees.
