Broadband dielectric spectroscopy for monitoring temperature-dependent chloride ion motion in BiOCl plates

Abstract The dielectric properties and electrical conduction mechanism of bismuth oxychloride (BiOCl) plates synthesized using chloramine-T as the chloride ion source were investigated. Thermally-activated structure rebuilding was monitored using broadband dielectric spectroscopy, which showed that...
