Abstract: | The anomalous shift in the maxima of the Shubnikov—de Haas transverse magnetoresistance oscillations in AlGaAs(Si)/GaAs with 2D electrons oriented in the [110] direction with respect to [{ie468-1}10] in large magnetic fields is explained by the formation of a lateral superlattice with an increase of the effective mass (m[110]* > m[{ie468-2}]*).
