    • More sophisticated approaches such as multivalley effective mass (MVEM) theories have been developed for impurities in Si (Ref. 15). We do not adopt such an approach in order to maintain a simple and clear physical picture, as approaches like MVEM mostly provide better estimates for the binding energy, but do not seriously alter the valley interference features.

    • Our results presented below on donor electron exchange do not differ significantly from those in Ref. 11 (where the 125 plane-wave basis set was used), though we present in Figs. 1 and 2 more detailed information on the charge distributions.

    • note
    • In MBE growth of donor arrays in Si, currently available technology does not allow differentiation for donor positioning among the two sites within one dimer (which are surface nearest neighbor to each other) of the Si (001) surface (Ref. 5). We believe a similar difficulty occurs for the 3D lattice nearest-neighbor sites.
