Energetic stability and crystal structures. a Enthalpy curves (relative to the ambient pressure distorted-3R phase) of the interested structures as a function of pressure. The inset shows the calculated enthalpy curves of newly found distorted-1T (relative to the distorted-3R) using different exchange-correlation functionals. Pressure-induced symmetrization of the distorted-3R (b) and distorted-1T structures (c)
