In ZrP 1.25 Se 0.75 , the superconducting transition temperature T c is increased from 5.8 K to 7.6 K when Sc atoms are partially substituted for Zr atoms having almost the same atomic radius as Sc atoms. Transport measurements show that holes are doped with substituting Sc atoms. The density of states in (Zr, Sc)P 1.25 Se 0.75 is derived from band structure calculations and its implication in the doping behaviour and the increase of T c is discussed.
