用光电光谱首次在纯锗中观察到受主A/sub 2/（E/sub瓦尔/ + 11.31 meV）和施主D（E/sub cond/-12.34 meV）基态的大的同位素位移。The shifts（）三角洲E/sup A/2 = + 21 +- 3.. Mu.. eV;..三角洲E/sup D/ = - 51 +- 3.. Mu.. eV）发生在在氘而不是氢中生长的锗晶体中。在浓度< 4 x 10/sup 11/ cm/sup-3/时观察到A/sub 2/和D。同位素位移是中心A/sub 2/和D含有氢的直接证据。
Large isotope shifts in the ground state of an acceptor A/sub 2/ (E/sub val/ + 11.31 meV) and a donor D (E/sub cond/-12.34 meV) have been observed for the first time with photoelectric spectroscopy in pure germanium. The shifts (..delta..E/sup A/2 = + 21 +- 3..mu..eV;..delta..E/sup D/ = - 51 +- 3..mu..eV) occur in germanium crystals grown in deuterium instead of hydrogen. A/sub 2/ and D are observed at concentrations < 4 x 10/sup 11/ cm/sup -3/. The isotope shift is a direct proof that the centers A/sub 2/ and D contain hydrogen.
