Latest Patents

Among his notable inventions, the **CDTe x-ray detector for use at room temperature** stands out. This improved x-ray detector utilizes a p-i-n CdTe homojunction device, featuring a high resistivity intrinsic layer made of CdTe. The growth of n- and p-doped CdTe layers is achieved through a photo-assisted process within a molecular beam epitaxial apparatus. The n-dopant of choice is indium, enhanced by an indium metal contact, while arsenic serves as the preferred p-dopant. The innovative use of a PAMBE formed mercury telluride contact layer is crucial in enhancing the ohmic contact to the p-layer, ultimately resulting in a device with a wide band gap (1.45 eV), enabling efficient operation at room temperature.

Another significant patent is his **method of purifying substrate from unwanted heavy metals**. This invention addresses the challenges posed by cadmium and tellurium impurities that typically arise as by-products of copper mining. The method involves creating a sacrificial layer of mercury telluride or mercury cadmium telluride on the substrate, followed by annealing it in an elevated temperature environment with an overpressure of mercury. This innovative approach allows for the removal of unwanted impurities that can adversely affect the performance of electronic circuitry.
