Nanoinjection Detectors and Imagers for Sensitive and Efficient Infrared Detection

A new class of short-wave infrared photon detectors, called Nanoinjection Photon Detectors, has been recently developed to address the main problem of using nanoscale features for light detection. Even though nanoscale sensors offer high sensitivity, their interaction with visible or infrared light is severely limited by their miniscule volume compared to the wavelength of light. Our nanoinjection detectors have highly sensitive nanometer sized electron injectors on a large and thick light-absorbing layers. These layers capture incoming light efficiently, and the nanoinjectors sense and amplify the signal. Due to the pairing of thick absorbers and nanoinjectors, high sensitivity and high efficiency can be achieved simultaneously.
