Latest Patents

One of Qi's latest patents is titled "Growth reactor systems and methods for low-temperature synthesis of nanowires." This invention describes a method for synthesizing silicon nanowires using a growth reactor that features a decomposition zone and a deposition zone. The process involves introducing a precursor gas into the decomposition zone, where it is disassociated to form activated species. These species then react with catalyst materials in the deposition zone, allowing for the deposition of nano-structured materials on a low melting point temperature substrate. This innovative approach ensures that the higher temperatures in the decomposition zone do not damage the molecular structure of the substrate.

Another notable patent is "Semiconductor device, method for manufacturing semiconductor single-walled nanotubes, and approaches therefor." This invention focuses on the formation and implementation of substantially semiconducting single-walled nanotubes. In this embodiment, these nanotubes are used to couple circuit nodes in electrical devices. The method includes selectively etching metallic nanotubes while preserving the semiconducting nanotubes, which enhances the performance of electronic circuits.
