Abstract:
An embodiment of a radiation detector includes a semiconductor-based blocking structure interposed between the detector's absorption region and at least one of its contact structures. The blocking structure is adapted to prevent minority carriers generated within the adjacent contact structure from reaching the absorption region, and may also prevent minority carriers generated within the absorption region near the contact structure from entering the contact structure. Majority carriers, on the other hand, may be substantially unimpeded by the blocking structure in moving from the absorption region to the contact structure. In an embodiment, the blocking structure has a higher effective energy gap than its adjacent contact structure and than the absorption region. The interface between the blocking structure and the absorption region may be graded, so that the effective energy gap decreases gradually between the blocking structure and the absorption region.
Abstract:
A multispectral radiation detector for detecting radiation in at least two spectral bands, comprises a substrate and a layer stack grown on the substrate. The layer stack comprises at least first and second photodiodes, each photodiode having at least one strain-compensating superlattice absorbing layer substantially lattice matched to adjacent layers of the detector. Each strain-compensating superlattice absorbing layer has an energy gap responsive to radiation energy in a corresponding spectral region and different from the energy gaps of other strain-compensating superlattice absorbing layers of the detector.
Abstract:
Techniques are provided for manipulating folder and file icons on a screen of an electronic device. A folder icon representing a folder is displayed on a screen, in a first mode, at a first location on the screen. The folder may contain a plurality of individual files and the folder icon is configured to indicate the plurality of individual files. An activation event is detected comprising a movement from the first location on the screen to a second location on the screen. In response to detecting the activation event, the folder icon is displayed on the screen along with icons representing the individual files on the screen. The screen may display the icons of the individual files as fanning out from the folder icon and/or may display the icons of the individual files entirely outside of the folder icon.
