Impurity's mo
WitrynaThe interaction between the Si 12 cage and the enclosed metal impurity is characterized as strongly delocalized bonding for M=Mo, W, while Cu tends to form directed bonds with selected atoms of the cage. Linear extension of the MSi 12 (Me=Mo,W) cells along their principal axes leads to units of the form M 2 Si 18. WitrynaThe impurity states introduced by substitutional doping of Mo 1−x M x Se 2 with group VB (M = V, Nb and Ta), and their effect on the thermoelectric properties were …
