KCl熔剂法制备的Cu2Se的热稳定性研究
Study on the Thermal Stability of Cu2Se Prepared by KCl Flux Method
摘要
Abstract
High quality Cu2Se thermoelectric crystal materials were prepared by using the KCl flux method combined with high-temperature melting and slow cooling technology.XRD analysis shows that the material contains α-and β-phases at room temperature.XPS analysis further indicates that during the preparation of Cu2Se,KCl flux slowly releases Se,improves crystal quality,and partially replaces Cu and Se in the lattice,which helps to enhance the thermoelectric transport performance of the material.The Seebeck coefficient and conductivity of the samples were tested at 300,450 K,and 600 K,respectively.The test results showed that the samples prepared by the flux method exhibited excellent service stability under the entire testing conditions,while maintaining a high carrier concentration.关键词
