Abstract

The growth of CdTe2O5 single crystals using a modified Bridgman technique in a RF furnace was attempted. A platinum/gold crucible was used to melt the powder mixture in a customized insulated chamber to provide an adequate vertical thermal gradient. Growths resulted in mica-shaped single crystals that were extracted and investigated. Some optical and electrical properties were studied. Czochralski (CZ) method was also tried but returned very small crystals at best, whereas evaporation of CdO and/or TeO2 presented another challenge.
