Tailoring coherent charge transport in graphene by deterministic defect generation
Nicola Melchioni, Federico Paolucci, Paolo Marconcini +4
Harnessing the wave-nature of charge carriers in solid state devices, electron optics investigates and exploits coherent phenomena, in analogy with optics and photonics. Typically,…
Direct Imaging of Coherent Quantum Transport in Graphene Heterojunctions
E. D. Herbschleb, R. K. Puddy, P. Marconcini +5
We fabricate a graphene p-n-p heterojunction and exploit the coherence of weakly-confined Dirac quasiparticles to resolve the underlying scattering potential using low temperature…
Unraveling quantum Hall breakdown in bilayer graphene with scanning gate microscopy
M. R. Connolly, R. K. Puddy, D. Logoteta +7
We use low-temperature scanning gate microscopy (SGM) to investigate the breakdown of the quantum Hall regime in an exfoliated bilayer graphene flake. SGM images captured during br…
