Advances in Chalcogenide Glasses (ChGs): Past, Present, and Future Applications

Since their birth in the early 1950s, ChGs are now recognized as multifunctional substances due to their suitability for applicationsApplications in diversified fields like memory applicationsApplications, fiberFiber opticsOptics, infrared sensingInfrared sensing devicesDevice, etc. ChGs fulfill multitask demands by playing the role of electronicElectronic materials in resistive switchingResistive switching, opticalOptical materials in fiberFiber sensingSensing, and ovonic materialsOvonic materials for phase-change memoriesPhase change memories. This makes them one of the fascinating members of the family of glassesGlass. A huge number of applicationsApplications in different areas like in applied branches of science (e.g., environmental science, space science, medical science) in addition to the conventional branches of science (physics, chemistry, biology) attracted the different groups of technologists/scientists of various developed and developing countries around the world. This chapter is designed to cover the advances in the field of ChGs from their early developing stage to the present time. An attempt has been made to cover past, present, and feature outlooks of ChGs based devicesDevice.
