摘要： Self-centering electromagnetic transducers, such as linear motors and generators, are disclosed. In one embodiment, an electromagnetic transducer includes an outer yoke made of a ferromagnetic material, and a coil assembly including a plurality of loops of electrically conductive wire, wherein the coil assembly is substantially surrounded by the outer yoke. The electromagnetic transducer further includes a magnet, and an inner yoke made of ferromagnetic material. The magnet is disposed within the outer yoke such that the coil assembly surrounds the magnet. The inner yoke is disposed within the magnet, and the magnet is free to translate. The electromagnetic transducer further includes at least one high-reluctance zone positioned within the outer yoke and/or the inner yoke. In some embodiments, the electromagnetic transducer includes one or more actuators that vary a width of one or more high-reluctance zones to change a spring rate of the electromagnetic transducer.

摘要： Embodiments of the present disclosure are directed to infrared detector devices incorporating a tunneling structure. In one embodiment, an infrared detector device includes a first contact layer, an absorber layer adjacent to the first contact layer, and a tunneling structure including a barrier layer adjacent to the absorber layer and a second contact layer adjacent to the barrier layer. The barrier layer has a tailored valence band offset such that a valence band offset of the barrier layer at the interface between the absorber layer and the barrier layer is substantially aligned with the valence band offset of the absorber layer, and the valence band offset of the barrier layer at the interface between the barrier layer and the second contact layer is above a conduction band offset of the second contact layer.
