Quenching of the quantum Hall effect in graphene with scrolled edges
Alessandro Cresti, Michael M. Fogler, Francisco Guinea +2
Edge nanoscrolls are shown to strongly influence transport properties of suspended graphene in the quantum Hall regime. The relatively long arc length of the scrolls in combination…
Unveiling the Landau Levels Structure of Graphene Nanoribbons
Rebeca Ribeiro, Jean-Marie Poumirol, Alessandro Cresti +5
Magnetotransport measurements are performed in ultraclean (lithographically patterned) graphene nanoribbons down to 70 nm. At high magnetic fields, a fragmentation of the electroni…
Magnetoresistance in Disordered Graphene: The Role of Pseudospin and Dimensionality Effects Unraveled
Frank Ortmann, Alessandro Cresti, Gilles Montambaux +1
We report a theoretical low-field magnetotransport study unveiling the effect of pseudospin in realistic models of weakly disordered graphene-based materials. Using an efficient Ku…
