We have studied structural phase transition in BaNi2As2 superconductor with the application of Phosphorous doping based on first principles calculations. Our results reproduce experimental findings and explain some of the experimental observations.

TLDR
The data analysis suggests that a doping-induced softening related to an in-plane Ni and As(P) phonon mode is responsible for the enhanced superconductivity in the tetragonal phase.
