Phase transitions and processes of disordering in crystals of the Cu6PS5I1 − xClx solid solutions
The temperatures of phase transitions in crystals of the Cu 6 PS 5 I 1 − x Cl x solid solutions have been determined and the x-T phase diagram of the crystals has been constructed using isoabsorption and polarization-optical measurements. The absorption edge of the Cu 6 PS 5 I 1 − x Cl x crystals ha...
