First-Principles Analysis on Structural Transition in BaNi2As2   Superconductor
  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.
