Latest Patents

One of his latest patents is the "Dual band gas imager." This semiconductor gas imaging device system includes one chip dual band Type II Superlattice (T2SL) detectors comprising two back-to-back diodes wherein the bias is flipped. The embodiment voltages range from +1V to -1V. In this design, only the detector with a negative voltage detects incoming infrared radiation. Another notable patent is related to a "Focal plane array with pixels defined by modulation of surface Fermi energy." In this patent, pixels in a focal plane array are defined by controlled variation of the Fermi energy at the surface of the detector array. By varying the chemical composition of the semiconductor at the detector surface, a corresponding variation in the surface Fermi energy is achieved, which in turn produces a variation in the electric field and electrostatic potential in the bulk semiconductor below the surface. This innovative method defines pixels by having one Fermi energy at the surface of each pixel and a different Fermi energy at the surface between pixels. The modulation of Fermi energy can also be controlled by applying different electrostatic potential voltages to the metal pads defining each pixel and to an interconnected metal grid covering the gaps between all the pixel metal pads. This approach obviates the need to etch deep trenches between pixels, resulting in a more manufacturable quasi-planar process without sacrificing performance.
