Illuminating Batteries, Semiconductors and 2D Materials with Correlative Raman Microscopy

This detailed presentation focuses on Raman microscopy combined with other methods, such as AFM, SEM and SHG, for the comprehensive characterization of energy storage devices, semiconductors and 2D materials.

Contents

This presentation describes the principles of 3D Raman imaging and the speaker shows in detail how to access chemical imaging at the highest spatial and spectral resolution. Comprehensive analyses of samples often require a combination of different techniques. Structural information on a sample’s surface can be obtained by Atomic Force Microscopy (AFM) or Scanning Electron Microscopy (SEM). Raman imaging can reveal its chemical composition and by combining the techniques, structural and chemical information can be easily acquired from the same sample position. These approaches are described and the power of correlative Raman-AFM and Raman-SEM imaging for analysis is illustrated in the contexts of energy storage devices, semiconductors and 2D materials. 

Learning Outcomes:

• Learn about the fundamentals of enhanced 3D Raman imaging at the highest spectral and spatial resolution.
• Be presented with evidence of how correlative Raman microscopy can provide a more complete understanding of a sample than single techniques in isolation.
