摘要

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 MWO4(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.
