A novel high-pressure polymorph of TaSi2
We report a novel high-pressure cubic cF24 phase of TaSi2 which is stable above 185 GPa through first-principles swarm intelligence structure search method. Results on enthalpy difference show that the structural transition of TaSi2 from the ambient hexagonal C40 phase to cF24 phase is first order w...
