Surface quantum oscillations in tellurium inversion layers

Calculation of surface quantum levels in tellurium inversion layers

“…Shubnikov de Haas (S d H) experiments have already been reported on tellurium inversion layers, created in M.I. S. structures, the surface being [0001] [2] or [1100] [3] planes. In the last case, for which the electric and the magnetic fields are parallel to the trigonal (c-) axis, a simple interpretation of the oscillation patterns has been given, which allows graphic determination of the energetical position of the (**) Laboratoire associé n° 17 au C.N.R.S.…”

“…It can be seen that two energetic levels, El, on the internal part of the sub-band, E2 on the external part, with wave vectors k, and k2, are induced by the potential well (the figure is not to scale). In fact, El and E2 must be simultaneous solutions of the Schrôdinger and Poisson equations, and are related to the Fermi level EF by (2).…”
