Electronic inhomogeneities in graphene: the role of the substrate interaction and chemical doping
A. Castellanos-Gomez, Arramel, M. Wojtaszek +5
We probe the local inhomogeneities of the electronic properties of graphene at the nanoscale using scanning probe microscopy techniques. First, we focus on the study of the electro…
Long Distance Spin Transport in High Mobility Graphene on Hexagonal Boron Nitride
P. J. Zomer, M. H. D. Guimarães, N. Tombros +1
We performed spin transport measurements on boron nitride based single layer graphene devices with mobilities up to 40 000 cmVs. We could observe spin transport…
Spin transport in high quality suspended graphene devices
M. H. D. Guimarães, A. Veligura, P. J. Zomer +4
We measure spin transport in high mobility suspended graphene (μ~ 10^5 cm^2/Vs), obtaining a (spin) diffusion coefficient of 0.1 m^2/s and giving a lower bound on the spin relaxati…
Reversible hydrogenation and band gap opening of graphene and graphite surfaces probed by scanning tunneling spectroscopy
Andres Castellanos-Gomez, Magdalena Wojtaszek, Arramel +2
The effect of hydrogenation on the topography and the electronic properties of graphene and graphite surfaces are studied by scanning tunneling microscopy and spectroscopy. The sur…
Transport Gap in Suspended Bilayer Graphene at Zero Magnetic Field
A. Veligura, H. J. van Elferen, N. Tombros +3
We report a change of three orders of magnitudes in the resistance of a suspended bilayer graphene flake which varies from a few ks in the high carrier density regime to several…
