Extremely low thermal conductivity and high thermoelectric performance in liquid-like Cu2Se1-xSx polymorphic materials
Zhao, Kunpeng; Blichfeld, Anders Bank; Eikeland, Espen; Qiu, Pengfei; Ren, Dudi; Iversen, Bo B; Shi, Xun; Chen, Lidong (Journal article, 2017)Recently, copper chalcogenides Cu2−xδ (δ = S, Se, Te) have attracted great attention due to their exceptional thermal and electrical transport properties. Besides these binary Cu2−xδ compounds, the ternary Cu2−xδ solid ... -
High thermoelectric performance and low thermal conductivity in Cu2−yS1/3Se1/3Te1/3 liquid-like materials with nanoscale mosaic structures
Zhao, Kunpeng; Zhu, Chenxi; Qiu, Pengfei; Blichfeld, Anders Bank; Eikeland, Espen; Ren, Dudi; Iversen, Bo B; Xu, Fangfang; Shi, Xun; Chen, Lidong (Journal article, 2017)Mosaic-crystal microstructure is one of the optimal strategies for decoupling and balancing thermal and electrical transport properties in thermoelectric materials. Herein, we successfully achieve the desired nanoscale ... -
