Abstract
Results of the investigation of transverse magnetoresistance temperature dependences in a single-crystal Cd specimen of [ 10 1 ¯ 0 ] orientation in the 8 T magnetic field has lead to the discovery of the temperature breakdown effect in the [ 11 2 ¯ 0 ] direction. It has been established, that phonons with wave vector, which width is equal or larger than the minimal distance between the contingent Fermi surface sheets, are needed for the implementation of this effect. Realization of this condition is possible only in the area of the maximal contingence of a ‘packet’ and the ‘monster’ corrugated cylinder of the second Brillouin zone on the upper hexagonal AHL plane.
