Thermoelectric properties of pressed pellets and pressureless sintering in the K2Bi8Se13-xSx system
(Affiliation: Department of Mechanical and Manufacturing Engineering, School of Engineering, University of Cyprus, Nicosia, CyprusAffiliation: Department of Chemistry, Michigan State University, East Lansing, MI 48824, United StatesCorrespondence Address: Tsiappos, A.Department of Mechanical and Manufacturing Engineering, School of Engineering, University of Cyprus, Nicosia, Cyprus, 2006)The solid solutions of ß-K2Bi8Se13 are an interesting series of materials for thermoelectric investigations because they possess very low thermal conductivity and relatively high power factor. Moreover, the sulfur-substituted ...
