Abstract Scope Materials can exhibit emerging properties when driven to highly nonequilibrium states using external stimuli such as optical lasers, electrical currents, or strains. To fully understand and manipulate these emergent properties, a comprehensive understanding of the fundamental processes is necessary. Structural characterization of materials with atomic spatial and temporal resolutions plays a critical role in this endeavor. Recently, the MeV Ultrafast Electron Diffraction (UED) user facility at SLAC National Accelerator Laboratory has emerged as a powerful platform for probing these highly nonequilibrium states under in-situ/operando conditions. The unique capability of MeV-UED enables real-time monitoring of the atomic-scale structural dynamics of materials under extreme conditions, shedding light on the underlying mechanisms governing the emergent properties. This talk will give an overview of the instrument's capabilities and highlight selected scientific findings of MeV-UED for in-situ/operando characterization of emerging materials.
