Phase transitions and pressure-induced amorphization of GeTe-Sb2Te3 compounds, which are used as phase-change optical memories (DVD)

Those materials are used as rewritable DVD due to their quick and reversible crystal/amorphous transition, under a laser pulse. We have demonstrated that pressure is an important A written bit (...)
