Magnetotransport studies of SiGe-based p-type heterostructures: problems of the effective mass determination
The Shubnikov–de Haas oscillations method of the effective mass extraction was illustrated by the magnetotransport
 properties investigation of two-dimensional hole gas in Si₁₋xGex (x = 0.13, 0.36, 0.95, 0.98) QWs. We
 have found that for certain samples our data cannot be fitted to...

| description | The Shubnikov–de Haas oscillations method of the effective mass extraction was illustrated by the magnetotransport
properties investigation of two-dimensional hole gas in Si₁₋xGex (x = 0.13, 0.36, 0.95, 0.98) QWs. We
have found that for certain samples our data cannot be fitted to standard theoretical curves in which the scattering
of charge carriers is described by conventional Dingle factor. It is demonstrated that reasons of deviations of
the experiment from the theory are as follows; (i) influence of the spin splitting on amplitude of SdH oscillations
maxima; (ii) extra broadening of the Landau levels attributed to existence of inhomogeneous distribution of the
carrier concentration; (iii) the influence of the concurrent existence of short and long-range scattering potentials;
(iv) the population of second energy level in the quantum well. The ways to calculate the effective masses m* of
holes in all cases are presented and values of m* are found for studied heterostructures.
