Electronic Transport Properties of Sodium Tungsten Bronzes Na_(0.54)WO_3 Single Crystals

摘要

Single crystals of ternary sodium tungsten bronzes have been prepared by the electrolysis of molten Na_2WO_4-WO_3 system.X-ray powder diffraction and energy dispersive spectroscopy results reveal that the obtained samples are of cubic phase with empirical formula of Na_(0.54)WO_3.Electrical resistivity measurement indicates a metallic conducting behavior without any anomaly from 5-300 K.
