Exploring interlayer Dirac cone coupling in commensurately rotated few-layer graphene on SiC(000-1)
C. Mathieu, E. H. Conrad, F. Wang +5
We investigate electronic band-structure images in reciprocal space of few layer graphene epitaxially grown on SiC(000-1). In addition to the observation of commensurate rotation a…
Charge spill-out and work function of few-layer graphene on SiC(0001)
O. Renault, A. M. Pascon, H. Rotella +7
We report on the charge spill-out and work function of epitaxial few-layer graphene on 6H-SiC(0001). Experiments from high-resolution, energy-filtered X-ray photoelectron emission…
Polarization sensitive surface band structure of doped BaTiO3(001)
J. E. Rault, J. Dionot, C. Mathieu +4
We present a spatial and wave-vector resolved study of the electronic structure of micron sized ferroelectric domains at the surface of a BaTiO3(001) single crystal. The n-type dop…
Polarization dependent chemistry of ferroelectric BaTiO3 (001) domains
Yanyu Mi, Gregory Geneste, Julien Rault +3
Recent works suggest that the surface chemistry, in particular, the presence of oxygen vacancies can affect the polarization in a ferroelectric material. This should, in turn, infl…
Effect of Oxygen Adsorption on the Local Properties of Epitaxial Graphene on SiC (0001)
C. Mathieu, B. Lalmi, T. O. Mentes +5
The effect of oxygen adsorption on the local structure and electronic properties of monolayer graphene grown on SiC(0001) has been studied by means of Low Energy Electron Microscop…
Microscopic correlation between chemical and electronic states in epitaxial graphene on SiC(000-1)
C. Mathieu, N. Barrett, J. Rault +6
We present energy filtered electron emission spectromicroscopy with spatial and wave-vector resolution on few layer epitaxial graphene on SiC$(000-1) grown by furnace annealing. Lo…
