A process for the fabrication of high efficiency thermoelectric materials using non-equilibrium synthesis routes is described. In one embodiment a molten alloy comprising a predetermined ratio of elements which will constitute the thermoelectric material is quenched at a cooling rate in excess of, for example, 10or 10K/s using a process such as melt spinning. The rapidly solidified particles are then placed into a mold having the desired size and shape. The particles in the mold are simultaneously compressed and sintered at elevated temperatures for a short duration using, for example, hot pressing or spark plasma sintering. The overall process provides improved microstructural control and greatly expands the accessible phase space, permitting the formation of dense, single-phase structures with nanosized grain boundaries and minimal or no impurity segregation. The process is especially advantageous for the formation of n- and p-type filled skutterudites which may be incorporated in thermoelectric devices.

A method for producing a long length high temperature superconductor wire, includes providing a substrate, having a surface with a length of at least 50 meters and a width. The surface supports a biaxially textured high temperature superconducting layer and the biaxially textured high temperature superconducting layer has a length and a width corresponding to the length and width of the surface of the substrate. The method includes irradiating the biaxially textured high temperature superconductor layer with an ion beam impinging uniformly along the length and across the width of the biaxially textured high temperature superconductor layer to produce a uniform distribution of pinning microstructures in the biaxially textured high temperature superconductor layer.

A superconducting magnetic energy storage device that can maintain a large ratio of the stored energy to the static energy loss, and has the ability to by-pass the current through a fast, high-voltage superconducting switch. More particularly, this invention relates to the design and application of novel high-voltage superconducting switch provided with a direct heating of the active superconducting layer through a metal substrate either by transport or by inductive current, and the protection of the superconducting layer by cryogenically-cooled metal-oxide-semiconductor field-effect transistors.

A radio frequency-assisted fast superconducting switch is described. A superconductor is closely coupled to a radio frequency (RF) coil. To turn the switch “off,” i.e., to induce a transition to the normal, resistive state in the superconductor, a voltage burst is applied to the RF coil. This voltage burst is sufficient to induce a current in the coupled superconductor. The combination of the induced current with any other direct current flowing through the superconductor is sufficient to exceed the critical current of the superconductor at the operating temperature, inducing a transition to the normal, resistive state. A by-pass MOSFET may be configured in parallel with the superconductor to act as a current shunt, allowing the voltage across the superconductor to drop below a certain value, at which time the superconductor undergoes a transition to the superconducting state and the switch is reset.
