Thermoelectric Properties of In0.2Ce0.1Co4Sb12.3 Ribbons Prepared by the Rapid-Quenching Technique

详细

The results of investigations of the thermoelectric properties of In_0.2Ce_0.1Co₄Sb_12.3 compound prepared by the rapid-quenching technique are presented. In the process of rapid-quenching, amorphous and partially crystallized thin ribbons are formed. The thus obtained ribbons serve as the initial material for fabricating bulk samples. However, the thermoelectric properties of the fabricated ribbons are practically unstudied. In this study, the thermopower and electrical resistivity of amorphous and crystalline ribbons are investigated for the first time at temperatures of 100–750 K. The range of stability of the amorphous state is determined, and the crystallization kinetics of amorphous ribbons is investigated.
