Spontaneous Formation of a Superconductor-Topological Insulator-Normal Metal Layered Heterostructure
2D materials with heterolayered structures beyond graphene are explored. A theoretically predicted superconductor-topological insulator-normal metal heterolayered structure is realized experimentally. The generated hybrid structure HfTe3/HfTe5/Hf has potential applications in both quantum-spin Hall effect-based and Majorana-based devices.
