    摘要: A semiconductor sensing device in which a sensing layer is exposed to a medium being tested in an area below and/or adjacent to a contact. In one embodiment, the device comprises a field effect transistor in which the sensing layer is disposed below a gate contact. The sensing layer is exposed to the medium by one or more perforations that are included in the gate contact and/or one or more layers disposed above the sensing layer. The sensing layer can comprise a dielectric layer, a semiconductor layer, or the like.

    摘要: A semiconductor device including a low conducting field-controlling element is provided. The device can include a semiconductor including an active region, and a set of contacts to the active region. The field-controlling element can be coupled to one or more of the contacts in the set of contacts. The field-controlling element can be formed of a low conducting layer having a sheet resistance between approximately 103 Ohms per square and approximately 107 Ohms per square. During direct current and/or low frequency operation, the field-controlling element can behave similar to a metal electrode. However, during high frequency operation, the field-controlling element can behave similar to an insulator.

    摘要: An improved light emitting heterostructure is provided. The heterostructure includes an active region having a set of barrier layers and a set of quantum wells, each of which is adjoined by a barrier layer. The quantum wells have a delta doped p-type sub-layer located therein, which results in a change of the band structure of the quantum well. The change can reduce the effects of polarization in the quantum wells, which can provide improved light emission from the active region.

    摘要: A solution for protecting an electronic device from an electrical surge using a mounting structure is provided. In particular, the mounting structure comprises a conductive material and is electrically connected to the protected electrical device. The conductive material and/or mounting structure can have one or more properties that prevent the mounting structure from adversely impacting operation of the electronic device during normal operation, but enables the mounting structure to provide an alternative electrical path during the electrical surge.
