Biography

Dr. Chen specializes in experimental Condensed Matter Physics focusing on quantum materials and structures. His recent research inlcudes spin, charge and thermal transport in quantum materials and structures. The TYC lab utilizes spin-polarized currents, pure spin currents, super-spin currents, and spin caloritronics to explore new science and applications in nanostructure. The new type of electronics, taking advantage of both charge and spin of conduction electrons, can be driven by electric field, magnetic field, or thermal gradient. Please visit  the TYC lab site on wix or google to learn more about our research. Dr. Chen got his B.S. from Peking University in China, and his PhD from the Johns Hopkins University.
