Abstract

Samples of HgCdTe with negative interaction gap determined by the pressure transition are studied in S.D.H. at 4.2K. Due to the density of states quantization with B, the Fermi level oscillations, taking into account the strong non parabolicity, are calculated. When an acceptor level lies near the Fermi level (E_F - E_A < 1 meV) an oscillation transfert of population between the C.B. and the acceptor states takes place. So the giant 0 oscillation seen in TMR and LMR configurations is clearely due to this transfert, because the LMR cannot exhibit mobility oscillation at low temperature without a spin flip. The calculation of the part due to this transfert agrees well in the case of 0 oscillation when the distance E_F - E_A is changed by mean of hydrostatic pressure. The contribution of the oscillations and average parts of C.B. concentration is in good agreement with the experimental results of the Hall coefficient.
