Femtosecond structural transformation of phase-change materials far from equilibrium monitored by coherent phonons

Multicomponent chalcogenides, such as quasi-binary GeTe–Sb(2)Te(3) alloys, are widely used in optical data storage media in the form of rewritable optical discs. Ge(2)Sb(2)Te(5) (GST) in particular has proven to be one of the best-performing materials, whose reliability allows more than 10(6) write–...
