Scanning near field optical (SNOM) microscopy image of a graphene flak obtained during the AFM workshop at the LNNano using the NanoIR2-s system of the facility. We are back to the business of imaging garphene and restart this research line here as well as in collaboration with the CNPEM.
We had a lot of fun during the workshop and the chance to teach AFM and related techniques (I gave 9 times a course on EFM/KFM). Furthermore, a lot of interaction with the user of the AFM facilities, I am still in collaboration with, was happening showing that we have an active Brazilian AFM community. The image above shows, how important state of the art instrumentation is, but also which kind of nice images we can obtained in science.
