Abstract:
A semiconductor infrared detector structured and arranged so that infringing infrared photons cause electric carriers to pass from a ground state in which the electric carriers are bound, to an excited state, thereby creating an electron-hole pair for generating a current in the detector, said detector comprising in order:a semiconductor substrate; an insulating material; a semiconductor material having patterns formed therein, wherein said patterns include at least one island connected to a plurality of bridges, said plural bridges being connected between polarization electrodes, wherein the plural bridges are lines with an approximately constant width, lp, and wherein the islands are zones with a width li larger than lp, said zones being arranged with infrared photons and electric carriers so that when the infrared photons are excited, the infrared photons cause the electric carriers to pass from a ground state in which the electric carriers are bound, to an excited state, thereby creating an electron-hole pair for generating a current in the detector.
