New publication: Low B Field Magneto-Phonon Resonances in Single-Layer and Bilayer Graphene
Nano Lett. 15, 1547 (2015)
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 field magneto-phonon resonances in high-quality exfoliated single-layer and bilayer graphene encapsulated in hexagonal boron nitride. These resonances allow us to extract characteristic effective Fermi velocities, as high as 1.20 × 106 m/s, for the observed “dressed” Landau level transitions, as well as the broadening of the resonances, which increases with the Landau level index.

New publication: Random Strain Fluctuations as Dominant Disorder Source for High-Quality On-Substrate Graphene Devices
Phys. Rev. X 4, 041019 (2014)
We perform systematic investigations of transport through graphene on hexagonal boron nitride (hBN) substrates, together with confocal Raman measurements and a targeted theoretical analysis, to identify the dominant source of disorder in this system. (more)
