Title: Christopher Shelton: Innovator in Metal Oxide Technologies
Introduction
Christopher Shelton is a notable inventor based in Raleigh, NC, with a focus on advanced materials and their applications. He holds a total of four patents, showcasing his contributions to the field of technology and innovation.
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 may be introduced from a doping source, such as an alloyed metal target, within the reaction chamber. The result is an electrically conductive metal oxide film deposited on the substrate, formed through a reaction between the metal particles and the reactive atmosphere. Related devices are also discussed in this patent.
Another significant patent is the development of a polaritonic hot electron infrared photodetector. This device is designed to detect infrared radiation and includes a first contact layer, a second contact layer, a first dielectric layer, a second dielectric layer, and a conductor layer. The first dielectric layer is positioned between the first and second contact layers, while the second dielectric layer is situated between the first dielectric layer and the second contact layer. The conductor layer is placed between the two dielectric layers. When infrared radiation strikes the conductor layer, it generates hot carriers that are injected from the conduction band of the conductor layer to that of the second contact layer.
