Abstract

The electrical transport measurement is made in Pb1-xSnxTe over various alloy compositions (x = 0.45 ∼ 0.80) and carrier concentrations (p = 3 × 1018 ∼ 3 × 1020 cm−3). The resistivity anomaly by soft-TO phonons is clearly demonstrated. The carrier concentration dependence of Tc at low concentration region ( < 1 × 1020 cm−3) is found to be smaller than a calculation by the interband electron-TO phonon interaction mechanism with isotropic two bands. The origin of the discrepancy is discussed.
