It is known that the atomic radius of vanadium is smaller than titanium. When vanadium substitutes titanium in TiN at the titanium sublattice, the lattice constant of TiN may lower a little. Therefore, the diffraction peak shifts to large angle direction. Download : Download full-size image; Fig. 1.
