摘要： Various embodiments comprise apparatuses and methods including a light sensor. The light sensor includes a first electrode, a second electrode, a third electrode, and a light-absorbing semiconductor in electrical communication with each of the first electrode, the second electrode, and the third electrode. A light-obscuring material to substantially attenuate an incidence of light onto a portion of the light-absorbing semiconductor is disposed between the second electrode and the third electrode. An electrical bias is to be applied between the second electrode, and the first and the third electrodes and a current flowing through the second electrode is related to the light incident on the light sensor. Additional methods and apparatuses are described.

摘要： Optically sensitive devices include a device comprising a first contact and a second contact, each having a work function, and an optically sensitive material between the first contact and the second contact. The optically sensitive material comprises a p-type semiconductor, and the optically sensitive material has a work function. Circuitry applies a bias voltage between the first contact and the second contact. The optically sensitive material has an electron lifetime that is greater than the electron transit time from the first contact to the second contact when the bias is applied between the first contact and the second contact. The first contact provides injection of electrons and blocking the extraction of holes. The interface between the first contact and the optically sensitive material provides a surface recombination velocity less than 1 cm/s.

摘要： Imaging apparatus (100, 200, 1200) includes a semiconductor substrate (312) and an array (202) of pixel circuits (1202, 1204), which are arranged in a matrix on the semiconductor substrate and define respective pixels (212) of the apparatus. Pixel electrodes (1208) are respectively coupled to the pixel circuits, and a photosensitive (1206) is formed over the pixel electrodes. A common electrode (1207), which is at least partially transparent, is formed over the photosensitive film. An opaque metallization layer (1214) is formed over the photosensitive film on one or more of the pixels and coupled in ohmic contact to the common electrode. Control circuitry (208, 1212) is coupled to apply a bias to the common electrode via the opaque metallization layer while correcting a black level of the output values from the pixels using the signals received from the one or more of the pixels over which the opaque metallization layer is formed.
