Presented are results of our ab initio study of the structural relaxation of diamond nanowires, with dodecahedral and cubododecahedral morphology, showing that the energetic and structural stability of a diamond nanowire is dependent on both the surface morphology and the crystallographic direction of the principal axis. Although all structures under consideration exhibited significant changes in the length and cross-sectional area, nanowires with the principal axis in the [110] direction appear less structurally favorable.
