| Popis: | The Green's function technique within the framework of a valence-force-field Hamiltonian has been used to study the vibrational properties of the donor–hydrogen complexes, for the donors P, As, and Sb in silicon. The A1 and E vibrational energies of the complex were investigated by adopting two atomic configurations corresponding to different positions for the hydrogen atom relative to the donor impurity. According to the currently accepted configuration H is bonded to a silicon atom. Another possibility is to assume that H is directly bonded to the donor impurity. We have shown that both models reproduce all the vibrational energies which have been measured for these pair complexes until now. |
