Abstract
The possibilities of electron/hole doping of two ternary arsenides, BaFe2As2 and BaNi2As2, via partial substitution at the arsenic position by 16 and 14 group elements, have been studied. While no substitution has been observed for chalcogens, BaFe2As2 incorporates Sb, Si, and Ge at the As site; BaNi2As2 incorporates Sb, Ge, Sn, and Pb. The observed results can be tentatively explained suggesting that 14 group elements are incorporated into the BaT2As2 structures as X6− 2 dumbbells.
