Surface enhanced covalency and Madelung potentials in Nb doped SrTiO (100), (110) and (111) single crystals
G. M. Vanacore, L. F. Zagonel, N. Barrett
The influence of surface enhanced covalency on the Madelung potential is experimentally investigated using angle-resolved photoemission for (100), (110) and (111) SrTiO surface…
Spatially resolved, energy-filtered imaging of core level and valence band photoemission of highly p and n doped silicon patterns
N Barrett, L F Zagonel, O Renault +1
An accurate description of spatial variations in the energy levels of patterned semiconductor substrates on the micron and sub-micron scale as a function of local doping is an impo…
Orientation dependent work function of in situ annealed strontium titanate
L F Zagonel, M Bäurer, A Bailly +5
We have used energy filtered x-ray photoelectron emission microscopy (XPEEM) and synchrotron radiation to measure the grain orientation dependence of the work function of a sintere…
Band Mapping in One-Step Photoemission Theory: Multi-Bloch-Wave Structure of Final States and Interference Effects
E. E. Krasovskii, V. N. Strocov, N. Barrett +3
A novel Bloch-waves based one-step theory of photoemission is developed within the augmented plane wave formalism. Implications of multi-Bloch-wave structure of photoelectron final…
