Аннотация

The large optical-quality MWO₄ (M = Zn, Cd) crystals of mass up to 14 (ZnWO₄) and 20 (CdWO₄) kg were grown by Low Thermal Gradient Czochralski Technique (LTG Cz). Crystallographic properties of MWO ₄(010) cleaved surface were evaluated by AFM and RHEED, and electronic structure of the surface was studied using XPS. A system of Kikuchi lines has been observed for cleaved MWO₄(010) by RHEED confirming high crystallographic quality of the surface. The XPS valence-band and core-level spectra of MWO₄(010) have been measured. The XPS measurements reveal that W and M atoms are in the formal valences 6+ and 2+, respectively, on cleaved MWO₄(010) surface.
