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…
Influence of the ferroelectric polarization on the electronic structure of BaTiO3 thin films
N. Barrett, J. Rault, I. Krug +5
Micrometric domains of precise ferroelectric polarization have been written into a 20 nm thick epitaxial thin film of BaTiO3(001) (BTO) on a Nb doped SrTiO3 (STO) substrate using P…
Evolution of defect signatures at ferroelectric domain walls in Mg-doped LiNbO3
Guillaume F. Nataf, Mael Guennou, Alexander Haußmann +2
The domain structure of uniaxial ferroelectric lithium niobate single crystals is investigated using Raman spectroscopy mapping. The influence of doping with magnesium and poling a…
