Abstract
We perform first principles total energy calculations to study the energetics, and the atomic structure of the adsorption of germane (GeH 4) molecules on the Ge(001)-c(2 × 4) surface. The adsorption of a GeH 4 unit occurs after its dissociation into a germanium trihydride (GeH 3) and a hydrogen atom and a subsequent decomposition into a germanium dihydride (GeH 2) subunit and H atoms. Consequently, we first consider the adsorption of GeH 2 in two different configurations; the on-dimer and the intra-row geometries. Similar to the adsorption of SiH 2 and GeH 2 on Si(001), it is found that the on-dimer site is more stable than the intra-row geometry by 0.13 eV. However, in the adsorption of a GeH 2 fragment together with two H atoms we find that the intra-row geometry is energetically more favorable, again, similar to the adsorption of SiH 2 and GeH 2 (plus two H atoms) on the Si(001) surface.
