Latest Patents
Robert P Devaty holds a patent for a method of operating p-i-n diodes and superlattice devices. This patent describes a technique for detecting far infrared light using semiconductor devices that have at least two doped layers, with adjacent doped layers separated by undoped layers. The method involves doping to levels that establish work functions at interfacial barriers, which are approximately equal to the photon energy of the far infrared light of the longest wavelength to be detected. The devices are forward biased, cooled to a temperature where thermal excitation of carriers in the doped layers is less than the work function, and exposed to far infrared light of a bandwidth that includes the selected longest wavelength. The photo current produced by the excitation of carriers over the interfacial barriers is then measured. This method can be applied to existing p-i-n diodes and superlattice structures, as well as devices fabricated to respond to specific far infrared wavelength bands.
