From: Universal amorphous-amorphous transition in GexSe100−x glasses under pressure
The pressure-volume equation of state for amorphous GexSe100−x.
The results obtained by AIMD (filled diamond symbols) are compared to the measured data of Ge20Se80 of Kalkan et al.8 and Skinner et al.23, Ge17Se83 and Ge8Se92 of Brazhkin et al.29 (open symbols). The solid lines represent third-order Birch-Murnaghan equation of state fits to the simulation data. Numerical and experimental data of Ge18Se82 and Ge10Se90 have been shifted by multiples of −10% for clarity.
