A topological phase buried in a chalcogenide superlattice monitored by a helicity dependent Kerr measurement

Richarj Mondal, Yuki Aihara, Yuta Saito +4

Chalcogenide superlattices (SL), formed by the alternate stacking of GeTe and Sb${}_2$Te${}_3$ layers, also referred to as interfacial phase change memory (iPCM), are a leading can…
