title = "Pressure-induced amorphization of quasibinary GeTe- Sb2 Te3: The role of vacancies",
abstract = "The authors demonstrate that the cubic phase of quasibinary GeTe- Sb2 Te3 alloys (GST), the material of choice in phase-change optical recording (such as digital versatile disk-random access memory) can be rendered amorphous by the application of hydrostatic pressure. The amorphization pressure depends on the GST composition. The pressure-induced amorphous phase possesses a local structure around Ge atoms similar to that of laser-amorphized GST. They argue that vacancies are crucial for the pressure-induced amorphization.",

note = "Funding Information: XAFS measurements were carried out at beamline ID24 at ESRF (Grenoble, France) under proposal HD-45. The authors are very thankful to Sebastien Pasternak, technician on ID24, for the optimization of the high temperature diamond anvil cell. The SPring-8 Ge XAFS results were obtained at beamline BL14B as part of the Nanotechnology Support Project of the Ministry of Education, Culture, Sports, Science and Technology. (Proposal No. 2003B0086-NXa-np-Na). The authors would also like to thankfully acknowledge numerous stimulating discussions with M. Wuttig. ",
