Phonon-mediated room-temperature quantum Hall transport in graphene
Daniel Vaquero, Vito Clericò, Michael Schmitz +14
The quantum Hall (QH) effect in two-dimensional electron systems (2DESs) is conventionally observed at liquid-helium temperatures, where lattice vibrations are strongly suppressed…
Fractional quantum Hall effect in CVD-grown graphene
M. Schmitz, T. Ouaj, Z. Winter +6
We show the emergence of fractional quantum Hall states in dry-transferred chemical vapor deposition (CVD) derived graphene assembled into heterostructures for magnetic fields from…
High mobility dry-transferred CVD bilayer graphene
Michael Schmitz, Stephan Engels, Luca Banszerus +4
We report on the fabrication and characterization of high-quality chemical vapor-deposited (CVD) bilayer graphene (BLG). In particular, we demonstrate that CVD-grown BLG can mechan…
Line Shape of the Raman 2D Peak of Graphene in Van Der Waals Heterostructures
Christoph Neumann, Luca Banszerus, Michael Schmitz +6
The Raman 2D line of graphene is widely used for device characterization and during device fabrication as it contains valuable information on e.g. the direction and magnitude of me…
Probing electronic lifetimes and phonon anharmonicities in high-quality chemical vapor deposited graphene by magneto-Raman spectroscopy
Christoph Neumann, Donatus Halpaap, Sven Reichardt +6
We present a magneto-Raman study on high-quality single-layer graphene grown by chemical vapor deposition (CVD) that is fully encapsulated in hexagonal boron nitride by a dry trans…
Ballistic transport exceeding 28 μm in CVD grown graphene
Luca Banszerus, Michael Schmitz, Stephan Engels +5
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…
Raman spectroscopy as probe of nanometer-scale strain variations in graphene
Christoph Neumann, Sven Reichardt, Pedro Venezuela +9
Confocal Raman spectroscopy is a versatile, non-invasive investigation tool and a major workhorse for graphene characterization. Here we show that the experimentally observed Raman…
