Zeeman Spectra of Arsenic and Antimony in Germanium in an Intermediate Magnetic Field

概要

論文の詳細を見る
The Zeeman spectra of arsenic and antimony donors in germanium were measured at liquid helium temperature with a static magnetic field along a [111] direction and up to 46 kOe. The Zeeman spectral lines of 2p_0, 2p_<±1> and 3p_<±1> were compared with the theory presented in a presented in a preceding paper. As a result, it was substantiated that the description of these donor levels can be well approximated by accounting only the longitudinal-axis component of the magnetic field for each velley, and also that the higher the levels the transformation from the weak approximation to the strong field approximation occurs at lower fields, The splitting of the ground states in the presence of a magnetic field was found to coincide with the theoretical prediction including the central-cell correction treated phenomenologically besides the magnetic field effect. On the basis of these comparison all the remaining absorption peaks were assigned to the hydrogen-like levels or the bound Landau levels.
