Secondary Electron (Energy) Matters

Speaker(s): Dr Cornelea Rodenburg

Abstract

What can secondary electrons (SE)s tell us about condensed matter?” This is a longstanding questions already asked in the context of energy materials as far back as WWII -  thus before electron microscopes became common place. Today’s ubiquitous Scanning Electron Microscopes (SEM)s  are known to exploit SEs for high resolution imaging of matter, while early works concentrated on SE spectroscopy to understand the effects of processing methods such a heat treatments or differences between photo sensitive materials.  

This seminar centers on how a combination of high resolution SE imaging and SE spectroscopy can be implemented in some modern SEMs and can reveal important meso-scale phenomena not observable by other characterization methods. The main focus will be on some of todays complex energy materials systems such as polymer and pervoskite solar cells or complex natural materials such as spider silks.
