With a total of 3 patents to his name, his work is paving the way for innovative applications in various technological domains.

Latest Patents

One of Guangyuan Lu's latest patents is a method for preparing a multi-layer hexagonal boron nitride film. This method involves preparing a substrate and a boron-containing solid catalyst, which is then annealed to melt the catalyst. By feeding a nitrogen-containing gas and a protecting gas into the atmosphere, the nitrogen reacts with the melted catalyst to form a multi-layer hexagonal boron nitride film on the substrate's surface. This innovative approach allows for the creation of films with lateral sizes in the order of inches and thicknesses ranging from several nanometers to several hundred nanometers, making it suitable for applications in two-dimensional material devices.

Another notable patent is the local carbon-supply device and method for preparing wafer-level graphene single crystal by local carbon supply. This method includes providing a local carbon-supply device and preparing a nickel-copper alloy substrate. The substrate is placed in the local carbon-supply device, which is then introduced into a chemical vapor-phase deposition system. A gaseous carbon source is introduced to grow the graphene single crystal on the substrate. The resulting graphene exhibits excellent crystallinity, simple preparation conditions, low cost, and good repeatability, which are essential for its application in various fields.
