Image sensor using photo-detecting molecule and method of operating the same

摘要

Provided is an image sensor using a photo-detecting molecule and a method of operating the image sensor. The image sensor may include a plurality of first electrodes disposed parallel to each other and a plurality of second electrodes disposed parallel to each other in a direction perpendicular to the first electrodes and above the first electrodes, and a plurality of subpixels formed in regions where the first electrodes cross the second electrodes. Each of the subpixels may comprise a photo-detecting molecule layer that may generate charges by absorbing light having a certain wavelength, a charge generation layer that may form a plurality of secondary electrons by receiving the charges from the photo-detecting molecule layer when a known voltage is applied between the first electrodes and the second electrodes, and a variable resistance layer, an electrical state of which is changed by receiving the secondary electrons generated from the charge generation layer.
