High Pressure Phase Transition of Copper Halides

Amaç & Hipotez:The structural changes within copper halides induced by pressure from zinc-blend to rock-salt passing through an intermediate tetragonal structure have been investigated using an effective interionic interaction potential.

📊

Temel Bulgular & Veri:The values of the phase transition pressures obtained by us for the copper halides are in good agreement with their available experimental data.

💡

Sonuç & Katkı:We have also investigated the equation of state, which shows an appreciable volume collapses at the phase transition pressures.
