MATERIALS SYSTEMS AND METHODS FOR OPTOELECTRONIC DEVICES

摘要

A photodetector is described along with corresponding materials, systems, and methods. The photodetector comprises an integrated circuit and at least two optically sensitive layers. A first optically sensitive layer is ovei at least a poition of the integrated circuit, and a second optically sensitive layer is over the fust optically sensitive layer Each optically sensitive layer is interposed between two electrodes. The two electrodes include a respective first electrode and a respective second electrode The integrated circuit selectively applies a bias to the electrodes and reads signals from the optically sensitive layers The signal is related to the number of photons received by the respective optically sensitive layer
