Ternary and quaternary Ge-S-Se-Sb-Te amorphous chalcogenide thin films for mid-infrared applications
International audience; Chalcogenide materials exhibit a unique portfolio of properties which has led to their wide use for nonvolatile memory applications such as optical storage (CD-RW and DVD-RAM), Conductive Bridging Random Access Memory or Phase Change Random Access Memory (PCRAM). More recently, thanks to huge electronic nonlinearities under electrical field application, chalcogenide glasses are considered as most promising materials to be used as Ovonic Threshold Switching (OTS) selectors [1]. Besides, thanks to high transparency window in the infrared range and large optical nonlinearities [2], chalcogenide alloys offer the opportunity of development of innovative mid-infrared (MIR)…
