X-ray photoelectron 3s spectra of transition metal oxides
V. R. Galakhov, S. Uhlenbrock, S. Bartkowski +6
We present metal 3s x-ray photoelectron spectra of different transition metal oxides. The values of the 3s exchange splitting for the 3d metal oxides are given as a function of the…
Combined study of KNbO3 and KTaO3 by different techniques of photoelectron and X-ray emission spectroscopy
A. V. Postnikov, B. Schneider, M. Neumann +5
The new results are presented of the experimental study of KNbO3 and KTaO3 by means of X-ray photoelectron spectroscopy, soft X-ray emission and X-ray fluorescence spectroscopy. In…
Structure Optimization and Frozen Phonons in LiNbO3
A. V. Postnikov, V. Caciuc, G. Borstel
The equilibrium ground-state structure of LiNbO3 in the paraelectric and ferroelectric phases is fully optimized in a first-principles calculation using the full-potential lineariz…
