Effective Mass of Holes in Ag 0.82 Sb 1.18 Te 2.18 and AgSbTe 2

Temperature dependences of the Hall and Seebeck coefficients in Ag0.82Sb1.18Te2.18 and AgSbTe2 are studied in the temperature range 4.2–320 K. It is found that the Hall coefficient in Ag0.82Sb1.18Te2.18 does not depend on the magnetic field, while for AgSbTe2, a weak dependence on the magnetic field is observed. The effective mass of holes (m* = 0.61m0) in Ag0.82Sb1.18Te2.18 is determined.
