In this letter, we report the observation of ballistic transport on micron length scales in
graphene synthesised by chemical vapour deposition (CVD). Transport measurements were …

We report on ballistic transport over more than 28 μm in graphene grown by chemical vapor
deposition (CVD) that is fully encapsulated in hexagonal boron nitride. The structures are …

We have investigated the electron transport in graphene at different carrier densities. Single
layer graphene was fabricated into Hall bar shaped devices by mechanical extraction onto a …

We describe a method for transferring ultra large-scale chemical vapor deposition-grown
graphene sheets. These samples can be fabricated as large as several cm 2 and are …

We present electronic transport measurements of single and bilayer graphene on
commercially available hexagonal boron nitride. We extract mobilities as high as 125 000 …

Graphene is a fascinating material for exploring fundamental science questions as well as a
potential building block for novel electronic applications. In order to realize the full potential …

We review recent experiments at Columbia on electronic transport in graphene
nanostructures. We define the graphene nanostructures by e‐beam lithography followed by …

The discovery of graphene, raises the prospect of a new class of nanoelectronic devices
based on the extraordinary physical properties,,, of this one-atom-thick layer of carbon …

An electrical conductor subjected to a magnetic field exhibits the Hall effect in the presence
of current flow. Here, we report a qualitative deviation from the standard behavior in electron …

We show that Coulomb drag in ultra-clean graphene double layers can be used for
controlling the on-and-off ratio for current flow by tuning the external gate voltage. Hence …
