摘要: A solid state cooler device is provided that includes a substrate, a first and second conductive pad disposed on the substrate, a first and second superconductor pad each having a side with a plurality of conductive pad contact interfaces spaced apart from one another and being in contact with a surface of respective first and second conductive pads, and a first and second insulating layer disposed between respective first and second superconductor pads, and respective ends of a normal metal layer. A bias voltage is applied between one of a first conductive pad or first superconductor pad and one of the second conductive pad or the second superconductor pad to remove hot electrons from the normal metal layer, and the contact area of the plurality of first and second conductive pad contact interfaces inhibits the transfer of heat back to the first and second superconductor pads.

摘要: This disclosure relates to Superconducting Quantum Interference Apparatuses, such as SQUID arrays and SQUIFs. A superconducting quantum interference apparatus comprises an array of loops each loop constituting a superconducting quantum interference device. The array comprises multiple columns, each of the columns comprises multiple rows connected in series, each of the multiple rows comprises a number of loops connected in parallel, and the number of loops connected in parallel in each row is more than two and less than 20 to improve a performance of the apparatus. It is an advantage that keeping the number of loops in parallel below 20 improves the performance of the apparatus. This is contrary to existing knowledge where it is commonly assumed that a larger number of parallel loops would increase performance.

摘要: Superconductivity is inhibited in selected portions of a high temperature superconductor ("HTS") material by patterning the selected portions with a resist. The patterned material is ion-bombarded to implant impurity ions in non-resist-bearing portions of the material. After low temperature annealing, the non-resist-bearing portions of the material lose their superconducting characteristics, but such characteristics are preserved in the material's resist-bearing portions. The material's crystalline structure is preserved, so additional layers can be epitaxially grown atop the inhibited material. Superconductivity is inhibited at a selected depth in a HTS material by subjecting the material to impurity ion bombardment at an energy level controlled to implant ions in the material at the selected depth. After low temperature annealing, the material loses its superconducting characteristics at the selected depth, but such characteristics are preserved at other depths (i.e. above and below the selected depth) and the material's crystalline structure is preserved. A multilayer HTS device and circuit structure can be made by initially depositing an HTS material on a substrate. Superconductivity is inhibited at a first selected depth in the material by ion-bombarding it at a first energy level controlled to implant impurity ions in the material at the first depth. The ion bombardment step is repeated for other selected depths by ion-bombarding the material at other energy levels controlled to implant impurity ions at the other depths. After low temperature annealing the material loses its superconducting characteristics at the selected depths, but such characteristics are preserved at other depths in the material, which retains its crystalline structure.
