Ov. Krasovska et al., THEORETICAL-STUDY OF OPTICAL AND ULTRAVIOLET PHOTOEMISSION SPECTRA OFSRTIO3, Solid state communications, 97(12), 1996, pp. 1019-1023
We present the results of the self-consistent ELAPW calculation of the
band structure of SrTiO3. The ground-state eigenvalues and wavefuncti
ons obtained within the local-density approximation (LDA) are used to
calculate optical spectra in the photon energy range up to 30 eV and t
he photoelectron energy distribution curves (EDC's) for (h) over bar o
mega=21.2 and 40.8 eV. The results are compared with optical, X-ray ab
sorption and ultraviolet photoemission measurements. A good agreement
with experiment is obtained.
