The establishment of modern quantum mechanics and condensed matter physics has greatly expanded humanity's understanding of materials, extending material research from the macroscopic scale to the microscopic scale. Novel quantum states such as superconductivity and the quantum Hall effect have been successively discovered, spawning new fields in the research and application of quantum material devices. The direction of quantum state and quantum devices mainly focuses on new materials and devices required for the future information industry, topological quantum state theory, condensed matter physics, and other fields. The research contents include thin film and low-dimensional material growth, heterojunction growth, interface control, device design, micro-nano processing, device characterization, etc.
