X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy provide chemical fingerprinting and structural information of 2D materials. The Thermo Scientific™ Nexsa™ Surface Analysis System eliminates sampling ambiguity by combining an XPS system with a Raman spectrometer to concurrently measure a material at the same point of analysis. This instrumentation has proven particularly useful in studying two-dimensional (2D) materials.

We demonstrate how the Thermo Scientific Nexsa XPS system:
- Reveals the chemical fingerprint of a 2D material;
- Maps the distribution of chemical states across the material;
- Assesses the structural phases of the material;
- Shows the potential to chemically locate the discrete nanofeatures in many 2D materials;
