Thermoelectric Properties of Bismuth Doped Lead Telluride PbTe:Bi
Journal Title: Фізика і хімія твердого тіла - Year 2014, Vol 15, Issue 2
Abstract
X-ray research was established with measurement of thermoelectric parameters (Seebeck coefficient α and specific conductivity σ) of lead telluride doped by bismuth. Textures’ presence in researched materials was witnessed; the phase of Pb1-xBix was identified and present in all doped samples irrespectively from the impurity content. This research demonstrates that introduction of bismuth in amounts (0,1-0,3) at. % promotes the growth of thermoelectric power α2σ of PbTe, due to increasing of Seebeck coefficient α and the electrical conductivity σ in comparison with undoped material.
