This work addresses the issue of determining the number of layers in few layers of graphene (FLG) flakes by cross‐comparison of several techniques: optical microscopy (OM), atomic force microscopy (AFM) and micro‐Raman (μR) spectroscopy. SL were preliminarily identified by μR spectroscopy, which allows an unambiguous distinction between monolayers, bilayers and multilayers from the shape and relative...
