Title: Cryogenic Electron Microscopy for the Physical Sciences

Host:  Prof. Kyle Shen

Abstract:  The 2017 Nobel Prize in Chemistry recognized the importance of cryo-electron microscopy in the life sciences where it has enabled high-resolution imaging of biomolecules. In the physical sciences, most efforts so far have focused on room temperature measurements where atomic resolution imaging and spectroscopy has been demonstrated. In this talk, I will discuss our developments of cryogenic scanning transmission electron microscopy to access emergent electronic states in solids as well as processes at liquid/solid interfaces. Focus will be on charge-ordered phases which permeate the phase diagrams of strongly correlated systems such as layered transition-metal dichalcogenides, colossal magnetoresistive manganites and cuprate high-temperature superconductors. Our techniques allow direct mapping of the microscopic nature of charge order in bulk materials as well as atomically engineered heterostructures.
