Title: Jon-Paul Maria: Innovator in Metal Oxide Technologies
Introduction
Jon-Paul Maria is a prominent inventor based in Raleigh, NC (US), known for his significant contributions to the field of metal oxide technologies. With a total of 16 patents to his name, he has made remarkable advancements in materials science and engineering.
Latest Patents
Among his latest patents is a method for creating high mobility doped metal oxide thin films. This innovative process involves providing a reactive deposition atmosphere with an oxygen concentration exceeding 20 percent in a chamber containing a substrate. A pulsed DC signal is applied to a sputtering target made of metal, allowing for the sputtering of metal particles. Additionally, a doping element can be introduced from a doping source, such as an alloyed metal target, within the reaction chamber. This method results in the deposition of an electrically conductive metal oxide film on the substrate, which is formed through a reaction between the metal particles and the reactive atmosphere.
Another notable patent is the development of an oxide heterojunction for detecting infrared radiation. This detector features an all-oxide, Schottky-type heterojunction, where the metal side is formed from dysprosium-doped cadmium oxide (CdO:Dy) and the semiconductor side is made from cadmium magnesium oxide (CdMgO). The detector operates by generating "hot" electrons through the excitation of surface plasmon polaritons by infrared radiation. These electrons can cross the Schottky-type barrier into the conduction band of the semiconductor, allowing for detection. The working wavelength of the infrared radiation can be adjusted by modifying the Dy content in the CdO, and the barrier height can be optimized by altering the composition of CdMgO.
