His work primarily focuses on the development of advanced thin films and fabrication techniques that enhance the electrical properties of materials.

Latest Patents

One of Junmin Xue's latest patents is titled "Heterolayered ferroelectric thin films and methods of forming same." This invention involves heterolayered thin films that consist of ferroelectric and piezoelectric layers with alternating crystal structures. The first layer features a rhombohedral crystal structure, while the adjacent second layer has a tetragonal crystal structure. These layers are designed to have a (100) preferred orientation, with the α-axis normal to the film's surface. The first layer can be a Zr-rich lead zirconate titanate layer, and the second layer can be a Ti-rich PZT layer. This innovative structure significantly improves the electrical properties of the thin films.

Another notable patent is "Mechanochemical fabrication of electroceramics." This method utilizes mechanochemical processes to produce electroceramics from oxide starting materials. The process begins with mixing industrial ceramic oxide powders, which are then reacted in a mechanochemical chamber. The mechanical energy, combined with thermal energy, activates the formation of electroceramic phases with perovskite structures and fine crystallinity. This technique allows for the fabrication of various PbO-based ceramics at sintering temperatures as low as 900°C.
