- 論文の詳細を見る
It is shown that the well-known Erginsoy's formula for scattering of electrons by neutral impurity is not valid for the electron scattering by neutralized acceptors in germanium or silicon. An alternative formula based on the positron-hydrogen scattering picture is presented and compared with the cyclotron resonance observation of the electron scattering by gallium and indium atoms in gemanium. From the temperature dependence of the scattering a unique determination of the effective Bohr radius of the neutral acceptor wave function is possible and the values of a,* ca. 35A for gallium and 55A for indium have been obtained. In addition, a promising possibility of observing electron cyclotron resonance in highly doped p-type materials is pointed out, which is due to the smaller scattering cross section for acceptors than that for donors.
