    • 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 ...

    • Thermoelectric properties of Cu2Se1−xTex solid solutions 

      Zhao, Kunpeng; Guan, Mengjia; Qiu, Pengfei; Blichfeld, Anders Bank; Eikeland, Espen; Zhu, Chenxi; Ren, Dudi; Xu, Fangfang; Iversen, Bo B; Xun, Shi; Chen, Lidong (Journal article, 2018)
      Binary Cu2Se and Cu2Te have gained great attention recently because of their interesting and abnormal physical properties, such as ultralow thermal conductivity, high carrier mobility, large effective mass of carriers and ...

    • Ultrahigh thermoelectric performance in Cu2−ySe0.5S0.5 liquid-like materials 

      Zhao, Kunpeng; Qiu, Pengfei; Song, Qingfeng; Blichfeld, Anders Bank; Eikeland, Espen; Ren, Dudi; Ge, Binghui; Iversen, Bo B; Shi, Xun; Chen, Lidong (Journal article, 2017)
      Liquid-like thermoelectric materials have recently received heightened attentions due to their exceptional thermal and electrical transport properties. As a typical example, Cu2−ySe has good electrical transport properties ...
