Ab initio electronic properties of dual phosphorus monolayers in silicon

Table 2 Listing of ab initio works in this field covering systems with 1/4 ML phosphorus density

δ refers to a single- δ-layer system, δ_n to n multiple adjacent δ layers, δδ to the bilayer systems considered here, and δ-wire to the dually confined monolayer nanowires considered in[21]. Note that further subtleties, such as the vertical separation and in-plane alignment considered here, could form a third (or fourth) tier of model nomenclature, but are omitted for brevity here. ^aRefers to this work.
