Superlattices consisting of stacked nano-sized GeTe and Sb<sub>2</sub>Te<sub>3</sub> blocks have attracted considerable attention owing to their potential for an efficient non-melting switching mechanism, associated with complex bonding between blocks. Here, we propose possible atomic models for the superlattices, characterized by different interfacial bonding types. Based on interplanar distances extracted from ab initio calculations and electron diffraction measurements, we reveal possible int ...[more]
