Identifying suitable substrates for high-quality graphene-based heterostructures
Luca Banszerus, Hendrik Janssen, Martin Otto +6
We report on a scanning confocal Raman spectroscopy study investigating the strain-uniformity and the overall strain and doping of high-quality chemical vapour deposited (CVD) grap…
Size quantization of Dirac fermions in graphene constrictions
B. Terrés, L. A. Chizhova, F. Libisch +9
Quantum point contacts (QPCs) are cornerstones of mesoscopic physics and central building blocks for quantum electronics. Although the Fermi wave-length in high-quality bulk graphe…
Pressure-induced commensurate stacking of graphene on boron nitride
Matthew Yankowitz, K. Watanabe, T. Taniguchi +2
Combining atomically-thin van der Waals materials into heterostructures provides a powerful path towards the creation of designer electronic devices. The interaction strength betwe…
