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…
Local spectroscopy of moiré-induced electronic structure in gate-tunable twisted bilayer graphene
Dillon Wong, Yang Wang, Jeil Jung +16
Twisted bilayer graphene (tBLG) forms a quasicrystal whose structural and electronic properties depend on the angle of rotation between its layers. Here we present a scanning tunne…
Characterization and manipulation of individual defects in insulating hexagonal boron nitride using scanning tunneling microscopy
Dillon Wong, Jairo Velasco, Long Ju +9
Defects play a key role in determining the properties of most materials and, because they tend to be highly localized, characterizing them at the single-defect level is particularl…
