Latest Patents
One of Lifeng Dong's latest patents is titled "Carbon nanotube with ZnO asperities." This invention provides a ZnO asperity-covered carbon nanotube (CNT) device along with a corresponding fabrication method. The method involves forming a substrate, growing CNTs from the substrate, conformally coating the CNTs with ZnO, annealing the ZnO-coated CNTs, and forming ZnO asperities on the surface of the CNTs in response to the annealing. The density of the ZnO asperities ranges from about 100 to 1000 per CNT, depending on the deposited ZnO film thickness and annealing parameters. The CNTs are coated with ZnO using various techniques, including sputtering, chemical vapor deposition (CVD), spin-on, or atomic layer deposition (ALD).
Another notable patent is the "Method for synthesizing nanoscale structures in defined locations." This method addresses challenges in nanoscale manufacturing by enabling the direct fabrication of composites that are useful for constructing electronic devices. It allows for the direct synthesis of nanotubes and arrays of nanotubes at defined locations, which is crucial for the development of advanced electronic components.
