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…
Spatial control of laser-induced doping profiles in graphene on hexagonal boron nitride
Christoph Neumann, Leo Rizzi, Sven Reichardt +6
We present a method to create and erase spatially resolved doping profiles in graphene-hexagonal boron nitride (hBN) heterostructures. The technique is based on photo-induced dopin…
Back action of graphene charge detectors on graphene and carbon nanotube quantum dots
C. Volk, S. Engels, C. Neumann +1
We report on devices based on graphene charge detectors (CDs) capacitively coupled to graphene and carbon nanotube quantum dots (QDs). We focus on back action effects of the CD on…
Low B Field Magneto-Phonon Resonances in Single-Layer and Bilayer Graphene
Christoph Neumann, Sven Reichardt, Marc Drögeler +6
Many-body effects resulting from strong electron-electron and electron-phonon interactions play a significant role in graphene physics. We report on their manifestation in low B fi…
