Growth of CdWO4 crystals by the low thermal gradient Czochralski technique and the properties of a (010) cleaved surface
The high-quality CdWO4 crystal of 80-90 mm in diameter and 180-200 mm long has been grown by Low Thermal Gradient Czochralski technique (LTG Cz). Large area atomically flat CdWO4(010) substrates have been prepared by cleavage. The CdWO4(010) surface is stable in the air up to 600 degrees C. At higher temperatures, the precipitation of WO3 and W19O55 oxides has been detected by RHEED. (C) 2014 Elsevier B.V. All rights reserved.
