    摘要: A superlattice layer including a plurality of periods, each of which is formed from a plurality of sub-layers is provided. Each sub-layer comprises a different composition than the adjacent sub-layer(s) and comprises a polarization that is opposite a polarization of the adjacent sub-layer(s). In this manner, the polarizations of the respective adjacent sub-layers compensate for one another. Furthermore, the superlattice layer can be configured to be at least partially transparent to radiation, such as ultraviolet radiation.

    摘要: A profiled contact for a device, such as a high power semiconductor device is provided. The contact is profiled in both a direction substantially parallel to a surface of a semiconductor structure of the device and a direction substantially perpendicular to the surface of the semiconductor structure. The profiling can limit the peak electric field between two electrodes to approximately the same as the average electrical field between the electrodes, as well as limit the electric field perpendicular to the semiconductor structure both within and outside the semiconductor structure.

    摘要: A device and method for managing terahertz and/or microwave radiation are provided. The device can comprise one or more field effect transistors (FETs) that each include at least one channel contact to a central region of the device channel of the FET. The frequency of the radiation managed by the device can be tuned/adjusted by applying a bias voltage to the FET. The radiation can be impinged on the device, and can be detected by measuring a voltage that is induced by the radiation. Further, the device can generate terahertz and/or microwave radiation by, for example, inducing a voltage between two edge contacts on either side of the device channel and applying the voltage to the channel contact.
