Imaging Quantum Interference in Stadium-Shaped Monolayer and Bilayer Graphene Quantum Dots
Zhehao Ge, Dillon Wong, Juwon Lee +10
Experimental realization of graphene-based stadium-shaped quantum dots (QDs) have been few and incompatible with scanned probe microscopy. Yet, direct visualization of electronic s…
Visualization and Control of Single Electron Charging in Bilayer Graphene Quantum Dots
Jairo Velasco, Juwon Lee, Dillon Wong +9
Graphene p-n junctions provide an ideal platform for investigating novel behavior at the boundary between electronics and optics that arise from massless Dirac fermions, such as wh…
Imaging electrostatically confined Dirac fermions in graphene quantum dots
Juwon Lee, Dillon Wong, Jairo Velasco +9
Electrostatic confinement of charge carriers in graphene is governed by Klein tunneling, a relativistic quantum process in which particle-hole transmutation leads to unusual anisot…
Nanoscale control of rewriteable doping patterns in pristine graphene/boron nitride heterostructures
Jairo Velasco, Long Ju, Dillon Wong +11
Nanoscale control of charge doping in two-dimensional (2D) materials permits the realization of electronic analogs of optical phenomena, relativistic physics at low energies, and t…
