(Bi2Te3)0:25(Sb2Te3)0:75 crystal structure improvements with excess Te as studied by AFM, SEM, EBSD and XRD
Published in Materials Science-Poland
(Bi2Te3)x(Sb2Te3)1−x solid solutions with x = 0:2, 0.25 and 0.3 − p type thermoelectric compounds with an excess of Tellurium dopant up to 4 wt% were crystallized. By increasing the Bi2Te3 content in the Bi-Sb-Te system, the hole concentration decreased and in consequence caused an optimum Seebeck coefficient and a decrease in electrical conductivi...
