Spherical, cylindrical and tetrahedral symmetries; hydrogenic states at high magnetic field in Si:P

Abstract


  • Phosphorous donors in silicon have an electronic structure that mimics the hydrogen atom, albeit on a

    larger length, smaller energy and smaller magnetic field scale. While the hydrogen atom is spherically

    symmetric, an applied magnetic field imposes cylindrical symmetry, and the solid-state analogue involves,

    in addition, the symmetry of the Si crystal. For one magnetic field direction, all six conduction-band valleys

    of Si:P become equivalent. New experimental data to high laboratory fields (30 T), supported by new

    calculations, demonstrate that this high symmetry field orientation allows the most direct comparison with

    free hydrogen.
