Beschreibungen/Notizen

• Thermoelectric and galvanomagnetic properties have been studied in n-Bi 2-x Sb x Te 3-y-z Se y S z and p-Bi 2-x Sb x Te 3-y-z Se y multicomponent solid solutions with various atomic substitutions in both sublattices of Bi 2 Te 3 . Anisotropy of the constant energy surface and charge carrier scattering was determined within the framework of a many-valley-model of energy spectrum using isotropic and anisotropic scattering mechanism for compositions of solid solutions with higher figure-of-merit.
