    摘要: A mid-infrared detector that uses a heavily doped material (e.g., indium arsenide) as a backplane to the detector structure to improve detector performance and fabrication cost. The infrared detector includes a substrate and a backplane of heavily doped material consisting of two or more of the following materials: indium, gallium, arsenic and antimony. The backplane resides directly on the substrate. The infrared detector further includes a photodetector (e.g., type-I or type-II strained layer superlattice (SLS) nBn photodetector, type-I or type-II SLS pn junction photodetector, a quantum-dot infrared photodetector, a quantum well infrared photodetector, a homogeneous material pn junction photodetector) residing directly on the backplane. Additionally, the infrared detector may include a metal structure residing directly on the photodetector. In this manner, the absorption of electromagnetic energy in the photodetector is enhanced.

    摘要: There is provided a photodiode array. The photodiode array includes a substrate that has an optical interface surface arranged, for accepting external input radiation into the substrate. A plurality of photodiodes are disposed at a substrate surface opposite the optical interface surface of the substrate. Each photodiode in the plurality of photodiodes includes a photodiode material that generates light into the substrate as a result of external input radiation absorption by the photodiode. There is aperiodic photodiode placement along at least one direction of the array.

    摘要: There is disclosed a method of preparing a photovoltaic device. In particular, the method comprises integrating epitaxial lift-off solar cells with mini-parabolic concentrator arrays via a printing method. Thus, there is disclosed a method comprising providing a growth substrate; depositing at least one protection layer on the growth substrate; depositing at least one sacrificial layer on the protection layer; depositing at least one photoactive cell on the sacrificial layer; etching a pattern of at least two parallel trenches that extend from the at least one photoactive cell to the sacrificial layer; depositing a metal on the at least one photoactive cell; bonding said metal to a host substrate; and removing the sacrificial layer with one or more etch steps. The host substrate can be a siloxane, which when rolled, can form a stamp used to integrate solar cells into concentrator arrays. There are also disclosed a method of making a growth substrate and the growth substrate made therefrom.

    摘要: A semiconductor device suitable for power applications includes a thyristor epitaxial layer structure defining an anode region offset vertically from a cathode region with a plurality of intermediate regions therebetween. An anode electrode is electrically coupled to the anode region. A cathode electrode is electrically coupled to the cathode region. A switchable current path that extends vertically between the anode region and the cathode region has a conducting state and a non-conducting state. An epitaxial resistive region is electrically coupled to and extends laterally from one of the plurality of intermediate regions. An FET is provided having a channel that is electrically coupled to the epitaxial resistive region. The FET can be configured to inject (or remove) electrical carriers into (or from) the one intermediate region via the epitaxial resistive region in order to switch the switchable current path between its non-conducting state and its conducting state.
