we use XPS (X-ray photoelectron spectroscopy) to get the information about the hybridization (sp2/sp3) and binding energy of a material at room temperature. What techniques can be used to probe a material to get temperature dependent binding energies?
When the material is layered on a substrate, we can continue to use XPS and Raman.
What otherwise do you mean about 2D? Are you suggesting the graphene film is free standing? Or are you asking about distinguishing information about bonding in-plane (xy) versus bonding between planes (z)?
you ca use raman and XPS for 2D materials binding energy and hybridization
Jeffrey J Weimer My question is mainly about doing the temperature dependent binding energy and hybridization studies of Graphene layer attached to substrates? Is it possible to change temperatures in XPS system?
