Temperature dependence of free path of some group of carriers in cadmium

The temperature dependence of the amplitude of oscillations of electron and hole dopplerons in cadmium were studied experimentally with the aim of determining the temperature dependence of the collision frequency of resonance carriers. The measurements were carried out at magnetic field directions near the hexagonal axis (0001) perpendicular to the plate surface. It is shown that in processing the measuring results it is necessary to use the formulas of a theory taking into account electron reflection from a metal surface. It was established that the recipprocal free path length of the electrons of the lentil reference point is proportional to T5; for the resonance holes of the monster it is proportional to T3. In an inclined field, a nonmonotonic variation of the oscillation amplitude of the electron doppleron with decreasing temperature was found. This phenomenon is attributed to the competition of the temperature-dependent collisional damping and the Landau collisionless damping
