Intervalley scattering in bismuth-antimony alloys at 4.2 K
Kirakozova L. A. , Minina N. Ya., Savin A. M.
A sharp decrease in the Dingle temperature has been observed during uniaxial compression in the alloy Bi0 9 Sb0A along the bisector axis. This decrease occurs because the intervalley scattering mechanism turns off upon the transition from a three-valley electron spectrum to a single-valley electron spectrum in the course of the deformation.
