Impact of Many-Body Effects on Landau Levels in Graphene
J. Sonntag, S. Reichardt, L. Wirtz +4
We present magneto-Raman spectroscopy measurements on suspended graphene to investigate the charge carrier density-dependent electron-electron interaction in the presence of Landau…
Dry-transferred CVD graphene for inverted spin valve devices
Marc Drögeler, Luca Banszerus, Frank Volmer +4
Integrating high-mobility graphene grown by chemical vapor deposition (CVD) into spin transport devices is one of the key tasks in graphene spintronics. We use a van der Waals pick…
Spin States Protected from Intrinsic Electron-Phonon-Coupling Reaching 100 ns Lifetime at Room Temperature in MoSe
Manfred Ersfeld, Frank Volmer, Pedro Miguel M. C. de Melo +6
We present time-resolved Kerr rotation measurements, showing spin lifetimes of over 100 ns at room temperature in monolayer MoSe. These long lifetimes are accompanied by an int…
From diffusive to ballistic transport in etched graphene constrictions and nanoribbons
Sowmya Somanchi, Bernat Terrés, Julian Peiro +5
Graphene nanoribbons and constrictions are envisaged as fundamental components of future carbon-based nanoelectronic and spintronic devices. At nanoscale, electronic effects in the…
Simulations on the influence of spatially-varying spin transport parameters on the measured spin lifetime in graphene non-local spin valves
Marc Drögeler, Frank Volmer, Christoph Stampfer +1
Spin transport properties of graphene non-local spin valve devices are typically determined from Hanle spin precession measurements by using a simplified solution of the one-dimens…
Dry transfer of CVD graphene using MoS-based stamps
Luca Banszerus, Kenji Watanabe, Takashi Taniguchi +2
Recently, a contamination-free dry transfer method for graphene grown by chemical vapor deposition (CVD) has been reported that allows to directly pick-up graphene from the copper…
