Latest Patents
One of his latest patents is titled "Stacked switchable element and diode combination with a low breakdown switchable element." This device comprises a semiconductor diode and a switchable element positioned in a stacked adjacent relationship. The semiconductor diode and the switchable element are electrically connected in series. The switchable element can transition from a low-conductance state to a high-conductance state in response to a low-density forming current and/or a low voltage.
Another significant patent is "Nanoparticle-based etching of silicon surfaces." This method involves texturing silicon surfaces to reduce the reflectivity of a silicon wafer for use in solar cells. The process includes filling a vessel with an etching solution that covers the silicon surface of a wafer or substrate. The etching solution consists of a catalytic nanomaterial and an oxidant-etchant solution. The catalytic nanomaterial may include gold or silver nanoparticles, while the oxidant-etchant solution contains an etching agent, such as hydrofluoric acid, and an oxidizing agent, such as hydrogen peroxide. The etching is performed for a specific duration, ensuring that the etched silicon surface has a reflectivity of less than about 15 percent.
