Crystal Orientation Dependent Oxidation Modes at the Buried Graphene-Cu Interface.
Philipp Braeuninger-Weimer, Oliver J Burton, Patrick Zeller, Matteo Amati, Luca Gregoratti, Robert S Weatherup, Stephan Hofmann
Aug 24, 2020
We combine spatially resolved scanning photoelectron spectroscopy with confocal Raman and optical microscopy to reveal how the oxidation of the buried graphene-Cu interface relates to the Cu crystallographic orientation. We...
Active metamaterial polarization modulators for the Terahertz frequency range
Stephen J. Kindness, Nikita W. Almond, Wladislaw Michailow, Binbin Wei, Philipp Braeuninger-Weimer, Stephan Hofmann, Harvey E. Beere, David A. Ritchie, Riccardo Degl’Innocenti

Abstract: Active control of chirality in the terahertz frequency range is of great importance in many scientific areas, which include research into fundamental optical phenomena, investigation of novel materials, spectroscopy...
Dirac-Point Shift by Carrier Injection Barrier in Graphene Field-Effect Transistor Operation at Room Temperature.
Sungsik Lee, Arokia Nathan, Jack Alexander-Webber, Philipp Braeuninger-Weimer, Abhay A Sagade, Haichang Lu, David Hasko, John Robertson, Stephan Hofmann
Dec 14, 2018
A positive shift in the Dirac point in graphene field-effect transistors was observed with Hall-effect measurements coupled with Kelvin-probe measurements at room temperature. This shift can be explained by the asymmetrical...
Freshwater monitoring by nanopore sequencing.
Lara Urban, Andre Holzer, J Jotautas Baronas, Michael B Hall, Philipp Braeuninger-Weimer, Michael J Scherm, Daniel J Kunz, Surangi N Perera, Daniel E Martin-Herranz, Edward T Tipper, Susannah J Salter, Maximilian R Stammnitz

A Peeling Approach for Integrated Manufacturing of Large Monolayer h-BN Crystals.
Ruizhi Wang, David G Purdie, Ye Fan, Fabien C-P Massabuau, Philipp Braeuninger-Weimer, Oliver J Burton, Raoul Blume, Robert Schloegl, Antonio Lombardo, Robert S Weatherup, Stephan Hofmann
Feb 07, 2019
Hexagonal boron nitride (h-BN) is the only known material aside from graphite with a structure composed of simple, stable, noncorrugated atomically thin layers. While historically used as a lubricant in powder form, h-BN layers...
Controlling Catalyst Bulk Reservoir Effects for Monolayer Hexagonal Boron Nitride CVD.
Engineering high charge transfer n-doping of graphene electrodes and its application to organic electronics.
