Abstract: A vacuum transistor includes a substrate and a first terminal formed on the substrate. A piezoelectric element has a second terminal formed on the piezoelectric element, wherein the piezoelectric element is provided over the first terminal to provide a gap between the first terminal and the second terminal. The gap is adjusted in accordance with an electrical field on the piezoelectric element.
