Most of the studies are performed at a low coverage with only a single or few NHx adatoms in the computational cell giving a coverage of up to around 0.25 ML. At higher coverage, lateral effects can modify the structures and shift the surface energies, changing which configuration is the most favorable. The structures from the earlier works were used as a basis and we extend them by increasing the coverage to the limiting 1 ML as expected by a complete ALD process.
