SDM4: High resolution spectroscopy, ultrafast spectroscopy

The energy resolution accessible with a monochromated electron beam in the TEM has opened the infrared regime to nanoscale or atomic-scale probes using electron energy-loss spectroscopy (EELS). Complementarily, the signal obtained from core-level excitations is now on par with the spectral resolution provided by X-ray absorption using synchrotron radiation. In parallel, the development of time-resolved spectroscopies opens a wide range of opportunities to explore the ultrafast electronic and structural dynamic response of materials subjected to optical and electronic excitations. This symposium is intended to experimentalists and theoreticians with EELS at high resolution, whether in energy (monochromated) and/or temporal (ultrafast, photon-induced near-field electron microscopy), as a key technique of their research. Contributions on instrumental development (detectors, TEM setups), complementary spectroscopies (e.g., cathodoluminescence), as well as materials science studies are encouraged.

Keywords: monochromated electron beam, electron energy-loss spectroscopy (EELS), cathodoluminescence (CL), ultrafast electron microscopy.
