Abstract
An existing superconducting material is rendered nonsuperconducting without a change in temperature by the generation of phonons which breakup the electron pairing within the superconducting material. The phonons are generated by a piezoelectric film deposited on the superconducting material. A high frequency signal is used to energize the piezoelectric film resulting in piezoelectric acoustic phonon generation within the superconducting material.
Claims10
An electrically switched superconductor comprising:
- a substrate;
- a superconductor material positioned on the substrate;
- and a patterned piezoelectric film positioned on the superconductor material to serve as a phonon generator to generate phonons in the superconductor material.
A method of electrically switching a superconductor, comprising:
- providing a superconductor material on a substrate;
- providing a piezoelectrically active material on the substrate;
- making electrical contact to the piezoelectrically active material so a high frequency signal may be applied to the piezoelectrically active material;
- and generating phonons in the superconductor material when the high frequency signal is applied to the piezoelectrically active material.
