Abstract

For EOIR nanotechnology sensors, we elucidated the quantum mechanical nature of the Einstein photoelectric effect in terms of a field-effect transistor (FET) made of Carbon NanoTube (CNT) semiconductors. Consequently, we discovered a surprising low-pass band gap property, as opposed to the traditional sharp band-pass band-gaps. In other words, the minimum amount of photon energy shining in the middle of CNT is necessary to excite the semiconductor CNT electrons. The conduction electron will spiral in a steady over the surface to minimize the collision recombination when travelling from the cathode end to the anode end by the asymmetric semiconductor-metal (using Pd or Al) Schottky interface effect for read out.
