    摘要: A full color complementary metal oxide semiconductor (CMOS) imaging circuit is provided. The imaging circuit comprises an array of photodiodes including a plurality of pixel groups. Each pixel group supplies 3 electrical color signals, corresponding to 3 detectable colors. The circuit also includes a color filter array overlying the photodiode array employing less than 3 separate filter colors. Each pixel group may be enabled as a dual-pixel including a single photodiode (PD) to supply a first color signal and stacked PDs to supply a second and third color signal. In one aspect, the color filter array employs 1 filter color per pixel group. In another aspect, the color filter array employees 2 filter colors per pixel group. In either aspect, the color filter array forms a checkerboard pattern of color filter pixels. For example, a magenta color filter may overlie the stacked PDs of each dual-pixel, to name one variation.

    摘要: A method is provided for forming a solution-processed metal and mixed-metal selenide semiconductor using selenium (Se) nanoparticles (NPs). The method forms a first solution including SeNPs dispersed in a solvent. Added to the first solution is a second solution including a first material set of metal salts, metal complexes, or combinations thereof, which are dissolved in a solvent, forming a third solution. The third solution is deposited on a conductive substrate, forming a first intermediate film comprising metal precursors, from corresponding members of the first material set, and embedded SeNPs. As a result of thermally annealing, the metal precursors are transformed and the first intermediate film is selenized, forming a first metal selenide-containing semiconductor. In one aspect, the first solution further comprises ligands for the stabilization of SeNPs, which are liberated during thermal annealing. In another aspect, the metal selenide-containing semiconductor comprises copper, indium, gallium diselenide (CIGS).

    摘要: An ultraviolet treatment method is provided for a metal oxide electrode. A metal oxide electrode is exposed to an ultraviolet (UV) light source in a humid environment. The metal oxide electrode is then treated with a moiety having at least one anchor group, where the anchor group is a chemical group capable of promoting communication between the moiety and the metal oxide electrode. As a result, the moiety is bound to the metal oxide electrode. In one aspect the metal oxide electrode is treated with a photoactive moiety. Exposing the metal oxide electrode to the UV light source in the humid environment induces surface defects in the metal oxide electrode in the form of oxygen vacancies. In response to the humidity, atmospheric water competes favorably with oxygen for dissociative adsorption on the metal oxide electrode surface, and hydroxylation of the metal oxide electrode surface is induced.
