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…
