제목 Monolithic Tandem Multicolor Image Sensor Based on Electrochromic Color-Radix Demultiplexing
초록 Optical data acquisition has been set as one of the milestones to testify the developments aimed at harnessing the full potential of the data processing capabilities of the advanced semiconductor technology. A highly promising approach to drive the level of acquisition beyond the current technological node is the vertical integration of multiple photodetectors. However, vertical integration requires the same level of circuit complexity as lateral integration from the incapability of monolithic integration. Here, we introduce a monolithic tandem multicolor photodetector which composed of vertically stacked p- and n-type graphene barristors. It exhibits variable anti-ambipolar charge transport behavior, which yields sensitive voltage-controlled photoconductive gain spectra. These electrical behaviors are utilized to fabricate an optoelectronic logic sensor that can demultiplex the desired color coordinate or wavelength in the constituent array with high color accuracy.
