DFT calculations of the coalescence between two AlN surfaces. (IMAGE)
Caption
a Schematic plot of the coalescence between two AlN nanowires and the surface bond lengths. b Schematic plot of the coalescence between two infinite AlN surfaces and the surface bond lengths. d//(Al-N) is the bond length of the Al-N bond formed by the surface Al and N atoms parallel to the surface, d//(Al) is the bond length of the parallel Al-N bond formed by the surface Al and subsurface N atom, and d//(N) is the bond length of the parallel Al-N bond formed by the surface N and subsurface Al atom. The notions for perpendicular bonds are similar. The subscripts e and c denote the bonds of the nanowire on the edge and near the corner, respectively. c The variation of the parallel bond lengths of nanowire and infinite surface as a function of the separation gap. d The variation of the perpendicular bond lengths of nanowire and infinite surfaces as a function of the separation gap.
