Title: Tracing Structural Dynamics in Metastable Materials Using Ultrafast Electron Diffraction
Location: 67-3111 Chemla Room
At Brookhaven National Laboratory, Dr. Jing Tao and her colleagues explore the intimate interactions of a particle or system's quantum characteristics, including charge, spin, and orbital and lattice degrees of freedom. These subtle phenomena can be exploited to develop exciting, cutting-edge technologies, including spintronics, high-temperature superconductors, and quantum computers. Existing experimental methods rely on examining materials at equilibrium—often before or after the useful behavior emerges or subsides—but Dr. Tao examines this quantum world with unprecedented speed and sensitivity. Dr. Tao uses ultrafast electron diffraction (UED) to excite custom-designed, complex materials and then probe them with an intense beam of electrons. Mapping non-equilibrium electronic states will reveal new fundamental rules of physics and help scientists design new, high-performing materials and technologies.
