Reactive-ion-etched graphene nanoribbons on a hexagonal boron nitride substrate
We report on the fabrication and electrical characterization of both single layer graphene micron-sized devices and nanoribbons on a hexagonal boron nitride substrate. We show that the micron-sizedExpand

Fabry-Pérot interference in gapped bilayer graphene with broken anti-Klein tunneling.
We report the experimental observation of Fabry-Pérot interference in the conductance of a gate-defined cavity in a dual-gated bilayer graphene device. The high quality of the bilayer graphene flake,Expand

Anomalous sequence of quantum Hall liquids revealing a tunable Lifshitz transition in bilayer graphene.
Bilayer graphene is a unique system where both the Fermi energy and the low-energy electron dispersion can be tuned. This is brought about by an interplay between trigonal warping and the band gapExpand

Characterizing wave functions in graphene nanodevices: Electronic transport through ultrashort graphene constrictions on a boron nitride substrate
We present electronic transport measurements through short and narrow (30x30 nm) single layer graphene constrictions on a hexagonal boron nitride substrate. While the general observation ofExpand

Raman spectroscopy on etched graphene nanoribbons
We investigate etched single-layer graphene nanoribbons with different widths ranging from 30 to 130 nm by confocal Raman spectroscopy. We show that the D-line intensity only depends on theExpand

Fast detection of single-charge tunneling to a graphene quantum dot in a multi-level regime
In situ-tunable radio-frequency reflectometry is used for fast charge-detection measurements on a graphene single quantum dot. The variable capacitance of our special matching network both grantsExpand
