We exploit the existence of an In adsorbate structure manifesting itself by a $(\\sqrt{3}\\times\\!\\sqrt{3})\\text{R}30^{\\circ}$ surface reconstruction observed in-situ by reflection high-energy electron diffraction. This In adlayer accommodates a maximum of 1/3 monolayer of In on the GaN surface and, under suitable conditions, can be embedded into GaN to form an In$_{0.33}$Ga$_{0.67}$N quantum sheet whose width is naturally limited to a single monolayer.
