Session 1: Amorphous Ionic and Electronic Conductors: Materials and Devices



Amorphous ionic and electronic conductors are among the most important/promising materials for many applications ranging from batteries to photovoltaics by passing through phase change memories. Substantial progress has been achieved during the last years, but many basic questions remain. New materials, sophisticated synthesis method, innovative characterization tools, novel device design as well as theoretical modeling are among the keys towards high capacity or highly efficient devices.


Topics covered will include, but are not limited to:

  • Chalcogenide memory materials. The utility of chalcogenide materials ranges from digital X-ray radiography to computer memory applications. The area is currently of very high interest both for materials science and optimization. Papers are sought for phase change memory (PCM) materials and conducting bridge (CBRAM) materials, as well as other topics involving chalcogenide glasses. We welcome papers on both technological and fundamental materials aspects.
  • Amorphous electronic and optical materials. The basic science of these systems, their photo-response and novel applications are all suitable topics for this session. Some examples include hydrogenated amorphous silicon and its PV and microbolometer (IR imaging) applications, amorphous phases of carbon and graphene.
  • Amorphous and nano-crystalline ionic conductors. These materials are the key for developing highly safe and high capacity all-solid batteries. Lithium and sodium containing chalcogenide/oxide glasses are among the best candidates. Papers are solicited particularly in the following fields: new glass composition, fabrication of bulk and thin films, characterization of materials and devices, etc.
