| Abstract: | Additional magnetoresistance and Hall effect oscillations have been revealed in the 2D hole system of an accumulation layer
on the Te
surface. The oscillation frequency was found to be equal to a linear combination of the frequencies of Shubnikov-de Haas
2D-hole conductivity oscillations in the two 2D subbands formed in a near-surface potential. The mechanism responsible for
these oscillations is related to the oscillating probability of intersubband scattering in transitions between Landau levels
of two size-and magnetic-field-quantized subbands, as they pass near the Fermi level.
