  • Doped carbon nanostructure field emitter arrays for infrared imaging
    Patent number: 7608824
    Abstract: An infrared imaging device and method for making infrared detector(s) having at least one anode, at least one cathode with a substrate electrically connected to a plurality of doped carbon nanostructures; and bias circuitry for applying an electric field between the anode and the cathode such that when infrared photons are absorbed by the nanostructures the emitted field current is modulated. The detectors can be doped with cesium to lower the work function.
