Detail investigation of thermoelectric performance and magnetic properties of Cs-doped Bi2Sr2Co2Oy ceramic materials
Özçelik, Bekir; Gürsul, Mehmet; Çetin, Gizem; Özçelik, Can; Torres, M. A.; Madre, María Antonieta; Sotelo, Andrés E. (Springer, 2021)Bi2Sr2-xCsxCo2Oy materials with 0 <= x <= 0.15, have been fabricated via the classical ceramic technique. XRD results have indicated that undoped and Cs-substituted samples are composed of Bi2Sr2Co2Oy phase as the major ... -
