KINETIC CONFINEMENT AND ZERO–ELECTRIC–FIELD BINDING IN HgCdTe ACCUMULATION LAYERS
2004
The effects of kinetic confinement and forming of surface bound states at a zero external electric field (ZEF) are studied experimentally (by the magneto-capacitance spectroscopy of Landau level method) and theoretically (in 8×8 Kane model). The self-consistent calculations we performed predict the existence of occupied kinetically bound but not true bound states at a zero interface electric field that is in agreement with experimental data. The capacitance oscillations at in 2D plane magnetic fields orientation we observed are associated with oscillations of continuum electrons screening length.
