Abstract
Official abstract text for this publication.
Various embodiment include optical and optoelectronic devices and methods of making same. Under one aspect, an optical device includes an integrated circuit having an array of conductive regions, and an optically sensitive material over at least a portion of the integrated circuit and in electrical communication with at least one conductive region of the array of conductive regions. Under another aspect, a film includes a network of fused nanocrystals, the nanocrystals having a core and an outer surface, wherein the core of at least a portion of the fused nanocrystals is in direct physical contact and electrical communication with the core of at least one adjacent fused nanocrystal, and wherein the film has substantially no defect states in the regions where the cores of the nanocrystals are fused. Additional devices and methods are described.
First claim
Opening claim text (preview).
What is claimed is: 1. An apparatus, comprising: a focal plane array including at least one optically sensitive layer formed on an underlying circuit, the circuit being patterned to measure and relay electronic signals on a pixel-by-pixel basis, the signal being indicative of light absorbed in a medium from which the focal plane array is made, the focal plane array being sensitized to become responsive to wavelengths absorbed in the at least one optically sensitive layer.
