摘要：

The vibrational modes of a recently proposed diatomic hydrogen complex in Si are examined through ab initio pseudopotential calculations. The hydrogen atom occupying the bond-centered position of the complex is found to have a higher stretching frequency of 2070 cm-1 as compared to 1480 cm-1 for the antibonding-centered hydrogen atom. This frequency shift results from the different orbital hybridizations of the two central Si atoms of the complex. © 1990 The American Physical Society.
