Abstract

Methods of optimizing the diameters of nanowire photodiode light sensors. The method includes comparing the response of nanowire photodiode pixels having predetermined diameters with standard spectral response curves and determining the difference between the spectral response of the photodiode pixels and the standard spectral response curves. Also included are nanowire photodiode light sensors with optimized nanowire diameters and methods of scene reconstruction.

Description

technical field [0001] This embodiment relates to nanowire devices, and more particularly to fabricating nanowire image sensors. Background technique [0002] Image sensors have a large number of sensor elements (pixels), typically greater than 1 million, in a Cartesian (square) grid. Commonly used color image sensors are fabricated with color filters configured in a Bayer setup. Figure 6 Examples of commonly used Bayer setups are illustrated in . The color scheme includes red, green and blue filters (RGB). The Bayer filter pattern is 50% green, 25% red and 25% blue, so it is also represented by GRGB or other arrangements such as RGGB. The green component is more than twice as large as the red or blue component to mimic the greater resolving power of the human eye for green light. Since each pixel is filtered to record only one of the three colors, the data from each pixel cannot fully determine the color on itself. To obtain a full color image, various demosaicing algo...
