Lifted graphene nanoribbons on gold: from smooth sliding to multiple stick-slip regimes
E. Tosatti, L. Gigli, R. Guerra, N. Manini, A. Vanossi
Picked up at one end, graphene nanoribbons can be made to slide on gold by atomic-force microscopy. Numerical simulations reveal, as a function of the lifting height, a surprising dynamic transition from smooth sliding to multiple stick-slip regimes, with a force asymmetry between the pushing and pulling directions.
