Abstract: This invention pertains to a device of a substrate and a ZrO2-based semiconductor disposed thereon and a method for depositing the semiconductor on the substrate. The semiconductor is typically in the form of a film of 1-20 weight % ZrO2 and 99-80 weight % In2O3 or SnO2 . The semiconductor is tunable in terms of optical transmission and electrical conductivity. Its transmission is in excess of about 80% over the wavelength range of 400-900 nm and its resistivity is from about 1.3×10−3 &OHgr;-cm to about 6.5×10−2 &OHgr;-cm. The deposition method is characterized by depositing in a chamber the semiconductor on a substrate by means of a physical vapor deposition whole maintaining a small oxygen pressure in the chamber.

Abstract: The order parameter of a superconductor is reduced by injecting spin-polarized carriers into the superconductor. The reduction in the order parameter is used to modulate the critical current of the superconductor. In a typical embodiment, a current is caused to flow through a superconductor. Spin polarized electrons are then injected into the path of the current in the superconductor by biasing a magnetic metal with respect to a terminal of the superconductor. The bias current may be varied to modulate the injection and thus the flow of current through the superconductor.
