Frequency selective electromagnetic detector

摘要

An apparatus, system, and method are disclosed for a frequency selective electromagnetic detector. In particular, the frequency selective electromagnetic detector includes a nanowire array constructed from a plurality of nanowires of different compositions. At least one nanoparticle-sized diameter thermoelectric junction is formed between the nanowires of different compositions. When a nanoparticle-sized diameter thermoelectric junction senses a photon, the nanoparticle-sized diameter thermoelectric junction emits an electrical pulse voltage that is proportional to an energy level of the sensed photon. In one or more embodiments, the frequency selective electromagnetic detector is a frequency selective optical detector that is used to sense photons having optical frequencies. In at least one embodiment, at least one of the nanowires in the nanowire array is manufactured from a compound material including Bismuth (Bi) and Tellurium (Te).
