Van der Waals epitaxy between the highly lattice mismatched Cu doped FeSe and Bi₂Te₃

Abstract:: We present a structural and density functional theory study of FexCu1-xSe within the three-dimensional topological insulator Bi2Te3. The FexCu1-xSe inclusions are single-crystalline and epitaxially oriented with respect to the Bi2Te3 thin film. Aberration-corrected scanning transmission electron microscopy and electron energy loss spectroscopy show an atomically-sharp FexCu1-xSe/Bi2Te3 interface. The FexCu1-xSe /Bi2Te3 interface is determined by Se-Te bonds and no misfit dislocations are observed, despite the different lattice symmetries and large lattice mismatch of ∼ 19%. First-principle calculations show that the large strain at the FexCu1-xSe /Bi2Te3 interface can be accommodated via van der Waals-like bonding between Se and Te atoms.
