WebThe phonon spectra of zinc-blende CuCl are studied as a function of pressure using density functional linear-response theory. A pressure-induced soft transverse-acoustic-phonon mode is identified. At 2.6 GPa, the TA phonon mode softens at the X point, initiating the phase transition from the zinc-blende structure CuCl-II to a cubic structure CuCl-IV.
