Thermoelectric Properties of the Silver Doped Lead Telluride PbTe:Ag
Journal Title: Фізика і хімія твердого тіла - Year 2014, Vol 15, Issue 2
Abstract
Thermoelectric parameters of the PbTe:Ag using the variational principle were calculated. Analyzed the behavior of the conductivity, Seebeck coefficient and thermal conductivity from the impurity content. Established that the impurity of silver gives p-type of conductivity for all samples, regardless of its content. Optimized material composition for the maximum thermoelectric figure of merit.
