Abstract:
Electron microscopy has long been an important tool in understanding the structure and function of materials. Electron microscopy provides unique capability for characterization of microstructure at the nanoscale including imaging, diffraction, and spectroscopy, complementing a variety of other approaches that provide more global information. In addition, recent developments have improved our capabilities significantly. For example, the first realization of combined spherical (Cs) and chromatic (Cc) aberration correction now provides increased spatial resolution and contrast in a variety of imaging modes in transmission electron microscopy. Likewise, the introduction of focused ion beam instruments as a core capability provides unique capability for preparation and interrogation of materials. In this presentation, the basic approaches of electron microscopy and their advantages as applied in materials science will be discussed. The use of these approaches will be illustrated through a series of examples in which electron microscopy has provided unique insight for energy related materials, including Li-ion batteries, high temperature superconductors, and fuel cell materials.
