Abstract Single- and multilayer graphene sheets (MLGSs) are projectile-resisting materials that can be bombarded by nanoparticles to produce graphene sheets of various sizes and distributions of nanopores. These sheets are used in a variety of applications, including DNA sequencing, water desalination, and phase separation. Here, the impact-withstanding efficiency of graphene nanosheets and the...
We investigate the optical response of graphene nanoribbons (GNRs) using broadband nonlinear generation and detection capabilities nanoscale junctions created at LaAlO3/SrTiO3 interface. GNR nanoclusters measured to be as small 1–2 GNRs in size are deposited on LaAlO3 surface with an atomic force microscope tip. Time-resolved probes reveal a strong, gate-tunable second third harmonic response, ...
Graphene nanoribbons can be folded into a double layer system keeping the two layers decoupled. In the quantum Hall regime folds behave as a new type of Hall bar edge. We show that the symmetry properties of the zero Landau level in metallic nanoribbons dictate that the zero energy edge states traversing a fold are perfectly transmitted onto the opposite layer. This result is valid irrespective...
