  • Systems, devices and methods for amplification of signals based on a cycling excitation process in disordered materials
    Patent number: 11670731
    Abstract: Methods, systems, and devices are disclosed for low noise and high efficiency photoelectric amplification based on cycling excitation process (CEP). In some aspects, a device for amplifying signals of light-induced photocurrent includes an anode connected to a positive terminal of a voltage source; a disordered material layer coupled to the anode, wherein the disordered material layer is structured to have a thickness of 100 nm or less; and a cathode coupled to the disordered material layer and connected to a negative terminal of the voltage source, in which the device is operable to amplify photoexcited carriers based on photon absorption to produce an external quantum efficiency of the device that is at least 100%.
    Type: Grant
