    摘要： A nanomechanical actuator/oscillator device and system are provided. The nanomechanical actuator/oscillator device comprising nanobimorphs, such as nanotubes, designed such that inducing a difference in charge density between the tubes (e.g. by biasing one tube positive with respect to the other with sufficient tube-to-tube contact resistance) induces lateral movement in the end of the bimorph, forming a nanoscale resonator, as well as a force sensor when operated in an inverse mode. A method of producing a novel nanobimorph structure with integrated electrodes is also provided.

    摘要： A method of producing a high temperature superconductor Josephson element and an improved SNS weak link barrier element is provided. A YBaCuO superconducting electrode film is deposited on a substrate at a temperature of approximately 800.degree. C. A weak link barrier layer of a nonsuperconducting film of N--YBaCuO is deposited over the electrode at a temperature range of 520.degree. C. to 540.degree. C. at a lower deposition rate. Subsequently, a superconducting counter-electrode film layer of YBaCuO is deposited over the weak link barrier layer at approximately 800.degree. C. The weak link barrier layer has a thickness of approximately 50 .ANG. and the SNS element can be constructed to provide an edge geometry junction.

    摘要： A technique for defining the active area of a high-T.sub.c superconductor Josephson junction uses an epitaxial slotted insulator patterned over the edge of the superconductor thin film-insulator bilayer. The superconductor/normal-metal/superconductor edge junction formed between the slotted insulator has a small active area. The counter electrode provided as an interconnect of the junction can therefore be wider than the active area of the edge junction since it can overlap onto the patterned slotted insulator. The use of the slotted insulator enables fabrication of junctions having resistances and critical currents in the desired range for high-T.sub.c superconductor circuits while enabling the use of wide, low inductance interconnects.

    摘要翻译： 用于定义高Tc超导体约瑟夫逊结的有源面积的技术使用在超导体薄膜 - 绝缘体双层的边缘上图案化的外延开槽绝缘体。 在开槽绝缘体之间形成的超导体/正常金属/超导体边缘连接器具有小的有效面积。 因此，作为结的互连提供的对电极可以比边缘连接的有源区域宽，因为它可以重叠到图案化的有槽绝缘体上。 使用开槽绝缘体能够制造具有在高Tc超导体电路的期望范围内的电阻和临界电流的结，同时能够使用宽的低电感互连。
