Interpretation of XPS O (1s) in Mixed Oxides Proved on Mixed Perovskite Crystals
TL;DR: In this article, the interpretation of X-ray photoelectron spectroscopy (XPS) signals in mixed perovskites was discussed, where the nonsingular O(1s) peak that occurs in the mixed oxides is due to the polarization of the oxygen valence electron density.

Growth of perovskite-type oxides (RE, Sr)(Al, Ta)O3 as substrates for GaN epitaxial growth (RE=La, Nd)
TL;DR: In this article, perovskite-type oxides (RE, Sr)(Al, Ta)O3 (RE=La, Nd) were investigated from solid-state reactions and grown by Czochralski method as substrates for GaN epitaxial growth.

TL;DR: In this article, Nitrogen-doped ZnO films (ZnO:N) were grown on (0.0, 0, 1) and (0,0, 1, 0) templates by plasma-assisted molecular beam epitaxy.

Growth and characterization of Tm, Ho-codoped Lu3Al5O12 single crystals by the Czochralski technique
TL;DR: Lu 3 Al 5 O 12 single crystals codoped with thulium and holmium were successfully grown by the Czochralski technique as mentioned in this paper, where a highly strained central core region caused by facet formation on the growth interface was observed.

TL;DR: In this article, the growth rate of nitrogen-doped zinc oxide (ZnO) film decreases as growth temperature increases from 500 up to 700°C since Zn-N bonds decompose.
