From: Co6Se8(PEt3)6 superatoms as tunable chemical dopants for two-dimensional semiconductors

The binding energy of Co6Se8(PEt3)5 and Co6Se8(CO)5 to WSe2 with 1–4 Re n-type dopant atoms, and 1–4 Nb p-type dopant atoms, and the binding enhancement energy of Co6Se8(PEt3)5-n(CO)n to the 4-doped Nb and Re WSe2 surfaces as compared to the undoped WSe2
