Latest Patents
Yanqing Jia holds a patent for the "Epitaxial lift-off process of graphene-based gallium nitride." This invention addresses the challenges associated with complex lift-off techniques, high costs, and the poor quality of lift-off GaN films. The process involves several key steps: first, growing graphene on polished copper foil using the chemical vapor deposition (CVD) method. Next, multiple layers of graphene are transferred onto a sapphire substrate. Following this, a GaN epitaxial layer is grown on the sapphire substrate using the metal organic chemical vapor deposition (MOCVD) method. Finally, the GaN epitaxial layer is lifted off and transferred to a target substrate using thermal release tape. This innovative approach utilizes graphene to alleviate stress caused by lattice mismatch, enabling easier transfer of the epitaxial layer.
