Intersubband-cyclotron combined resonance in a surface space-charge layer
In a magnetic field tilted with respect to the surface of Si, combined resonance transitions have been observed, resulting from a coupling of Landau levels and subband states. Because of some unexplained features in the observations, we analyze what one should expect on theoretical grounds. We conclude that unexplained discrepancies between theory and experiment still exist, which may indicate that collective effects are playing a role. © 1981
One-dimensional hydrogenic atom in an electric field with solid-state applications
A Hamiltonian describing a one-dimensional Coulomb field with an electric field in the same direction is useful for the discussion of electrons outside a free surface of liquid helium [1,2] and also for the study of far-infrared emission from Si inversion layers [3]. We present both a semi-classical and a WKB solution to the problem, which exhibits many of the features found experimentally. © 1977
