On the basis of monocrystals doped with copper PbSb2T e4, the paper investigates
the Hall kinetic coefficients, conductivity and thermopower and their anisotropy in the
temperature range from 77 to 450 K. The analysis of the temperature dependence of the
kinetic coefficients shows the necessity of taking into account the complex structure of the
valence band. It reveals a strong anisotropy of the thermoelectric power, indicating a mixed
scattering mechanism of holes. The study presents estimations of the scattering parameters
reff.
ii , the mass density of states m∗
d, the chemical potential mu0 and the energy gap E0
between the subbands of the valence band.
