    摘要: A solid state cooler device is disclosed that comprises a first normal metal pad, a first aluminum layer and a second aluminum layer disposed on the first normal metal pad and separated from one another by a gap, a first aluminum oxide layer formed on the first aluminum layer, and a second aluminum oxide layer formed on the second aluminum layer, and a first superconductor pad disposed on the first aluminum oxide layer and a second superconductor pad disposed on the second aluminum oxide layer. The device further comprises a first conductive pad coupled to the first superconductor pad, and a second conductive pad coupled to the second superconductor pad, wherein hot electrons are removed from the first normal metal pad when a bias voltage is applied between the first conductive pad and the second conductive pad.

    摘要: One example includes a method for making a switch. The method includes forming an insulating layer over a substrate. The method also includes forming a resistive heating material over the insulating layer. The method also includes depositing a thermally conductive electrically insulating barrier layer over the heating material. The method also includes forming a phase-change material (PCM) component over the barrier layer spaced apart and proximal to the resistive heating material. The method also includes forming a quench layer proximal to at least one of the resistive heating material and the PCM component. The method further includes forming conductive lines from ends of the PCM component and control lines from ends of the resistive heating material.

    摘要: A radio frequency (RF) filter includes a substrate, first and second dielectric layers formed on first and second portions of the substrate, a ground plane formed on a third portion of said substrate, a carbon nanotube array, and first and second electrodes. The third portion of the substrate includes, at least in part, the area between the first and second portions thereof. The carbon nanotube array is formed on a portion of said ground plane between the first and second dielectric layers. The first and second electrodes are formed on the first and second dielectric layers, such that an RF signal may be input to and output from the carbon nanotube array via the first and second signal guides. A third electrode is disposed over the carbon nanotube array and is used to voltage bias the array.
