Metavalent Bonding in Layered Phase‐Change Memory Materials (Adv. Sci. 15/2023)
Metavalent Bonding In article number 2300901, Wei Zhang, Matthias Wuttig, and co‐workers elucidate how metavalent bonding (MVB) develops across the so called van der Waals (vdW)‐like gaps in layered Sb2Te3 and Ge–Sb–Te alloys. By tailoring the degree of MVB across the gaps via uniaxial strain, a large variation of optical reflectivity can be obtained, enabling potential photonic applications.
