a, b Schematic and cross-sectional scanning transmission electron microscopy (STEM) image of Bi2Se3/monolayer NbSe2 heterostructure on bilayer graphene. A BiSe interfacial layer is formed at the heterojunction. Reproduced, with permission of Springer Nature, from ref. 206. c, d STEM images of Fe(Te,Se)/Bi2Te3 heterostructure. The schematic overlay in (d) highlights the epitaxial interface with no reconstruction. Reproduced, with permission of Wiley, from ref. 205.
