Enhanced Thermoelectric Performance through Tuning Bonding Energy in Cu2Se1–xSx Liquid-like Materials
Zhao, Kunpeng; Blichfeld, Anders Bank; Chen, Hongyi; Zhang, Tiansong; Zhu, Chenxi; Ren, Dudi; Hanus, Riley; Qiu, Pengfei; Iversen, Bo B; Xu, Fangfang; Snyder, G. Jeffrey; Xun, Shi; Chen, Lidong (Journal article; Peer reviewed, 2017)Thermoelectric materials require an optimal carrier concentration to maximize electrical transport and thus thermoelectric performance. Element doping and composition off-stoichiometry are the two general and effective ... -
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 ...
