Journal ArticleDOI
Intrinsic and extrinsic corrugation of monolayer graphene deposited on SiO 2
V. Geringer,Marcus Liebmann,Tim Echtermeyer,S Runte,Manuel J. Schmidt,R Rückamp,Max C. Lemme,Markus Morgenstern +7 more
TL;DR: A detailed analysis shows that the long-range corrugation of the substrate is also visible on graphene, but with a reduced amplitude, leading to the conclusion that the graphene is partly freely suspended between hills of the substrates.
Journal ArticleDOI
Synthesis of Graphene on Silicon Dioxide by a Solid Carbon Source
Jens Hofrichter,Bartholoma us N Szafranek,Martin Otto,Tim Echtermeyer,M. Baus,Anne Majerus,V. Geringer,Manfred Ramsteiner,Heinrich Kurz +8 more
TL;DR: The presented approach allows for mass fabrication of polycrystalline graphene without transfer steps while using only CMOS compatible process steps.
Journal ArticleDOI
Bistability and oscillatory motion of natural nanomembranes appearing within monolayer graphene on silicon dioxide.
T. Mashoff,Marco Pratzer,V. Geringer,Tim Echtermeyer,Max C. Lemme,Marcus Liebmann,Markus Morgenstern +6 more
TL;DR: Graphene flakes are shown to provide natural nanomembranes of diameter down to 3 nm within its intrinsic rippling, which might lead to a completely novel approach to controlled quantized oscillations or single atom mass detection.
Journal ArticleDOI
Wave-Function Mapping of Graphene Quantum Dots with Soft Confinement
D. Subramaniam,Florian Libisch,Yan Li,Christian Pauly,V. Geringer,R. Reiter,T. Mashoff,Marcus Liebmann,Joachim Burgdörfer,Carsten Busse,Thomas Michely,Riccardo Mazzarello,Marco Pratzer,Markus Morgenstern +13 more
TL;DR: It is found that the interaction with the substrate near the edge of the island gradually opens a gap in the Dirac cone, which implies soft-wall confinement, which results in highly symmetric wave functions.
Journal ArticleDOI
Bistability and oscillatory motion of natural nano-membranes appearing within monolayer graphene on silicon dioxide
T. Mashoff,Marco Pratzer,V. Geringer,Tim Echtermeyer,Max C. Lemme,Marcus Liebmann,Markus Morgenstern +6 more
TL;DR: In this article, it was shown that a monolayer of graphene on SiO2 provides natural, ultra-small membranes of diameters down to 3 nm, which are caused by the intrinsic rippling of the material.
