Abstract:

A thermodynamic study describing relative stability of different systems solid and liquid at equilibrium involved in the growth of semiconductor nanowires is reported. A number of stable and metastable phase diagrams, taking into account the size and the shape of condensed phases are calculated for the two binary systems Au-Si and Au-Ge.
