Latest Patents

Frederick Scholl holds a patent for a wavelength-selective photodetector. This invention features a heterojunction photodiode with improved wavelength-selectivity and risetime. The design addresses the problem of short-wavelength diffusion-tail response by incorporating a barrier layer of higher bandgap than that of the window layer. This barrier layer prevents high-energy photocarriers generated in the window layer from diffusing to the PN junction. In one embodiment, the n-type substrate, active, barrier, and window layers are initially grown. The window layer is then coated with an opaque oxide, and a window is opened in the oxide layer. A p-type dopant is diffused heavily through the opening, forming a PN junction in the barrier layer. The depletion region extends through the remaining n-type region of the barrier layer and into the active layer, where photocarriers are generated by photons passing through the window-opening.
