“…The importance of the experimental determination of the effective mass and g -factor in systems with a sophisticated dispersion law, to which the structures based on HgTe belong, is beyond doubt. The previously obtained experimental values of the g- factor and effective mass for HgTe quantum wells are contradictory and depend on the width of the quantum well and the electron density [ 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 ]. It was previously noted [ 39 , 40 , 41 , 42 ] that there is a problem of accordance between theoretical and experimental estimates of the effective mass in such QWs.…”
