Interfacial phase change memory （iPCM） based on GeTe and Sb2Te3 superlattices （SLs） is an emerging contender for non-volatile data storage applications. A detailed knowledge of the atomic structure of these materials is crucial for further development of SLs and for a better understanding of the res...
