Quantum tunneling photodetector array including electrode nano wires

A method of generating an image comprising the steps of:

• providing a quantum tunneling photodetector array comprising:
• an array of pairs of opposing first and second electrodes, the array of opposing first and second electrodes comprising a cross-grid of a first set of electrode nano wires and a second set of electrode nano wires, such that the first and second electrodes are constituted as opposing sections of the electrode nano wires of the first and second sets at projected cross-points of the cross-grid,
• a photo-sensitive insulating material disposed between the opposing first and second electrodes of the respective pairs, and
• an electrical circuit for detecting photo-assisted quantum tunneling currents between the opposing first and second electrode of the respective pairs;
• detecting photo-assisted quantum tunneling currents between opposing first and second electrodes of respective ones of the array of pairs of the opposing first and second electrodes;
• and
• generating the image based on the respective detected photo-assisted tunneling currents between the opposing first and second electrodes.
