Autor: Nikolaievskyi, D., Torregrosa, M., Merlen, A., Clair, S., Chuzel, O., Parrain, J. -L., Neisus, T., Campos, A., Cabie, M., Martin, C., Pardanaud, C.

Richness and complexity of Raman spectra related to graphene materials is established from years to decades, with, among others: the well-known G, D, 2D,... bands plus a plethora of weaker bands related to disorder behavior, doping, stress, crystal o

We report on an alternative route based on nanomechanical folding induced by AFM tip to obtain weakly interacting multi-layer graphene (wi-MLG) from a chemical vapor deposition (CVD) grown single-layer graphene (SLG). The tip first cuts, then pushes
