摘要：

The phonon heat conductivity k (ph) in Bi(1 - x) Sb (x) (x = 0.04-0.12) alloys is investigated in the temperature range of 6-60 K. The results are compared with the theory of solids at low temperatures, and the basic sources of phonon scattering are revealed. It is shown that phonon scattering at local mass changes dominates over other sources. The dependences of k (ph) on composition are considered at temperatures of 60 and 90 K, and it is found that the normal N processes substantially affect the phonon scattering under these conditions. The donor-impurity effect on heat conductivity of Bi(0.88)Sb(0.12) is considered, and the heat resistance caused by the phonon scattering at impurity centers is singled out.
