Scanning tunneling microscopy of interface properties of Bi2Se3 on FeSe

Journal Article


Abstract


  • We investigate the heteroepitaxial growth of Bi2Se3 films on FeSe substrates by

    low-temperature scanning tunneling microscopy/spectroscopy. The growth of Bi2Se3 on FeSe

    proceeds via van der Waals epitaxy with atomically flat morphology. A striped moire pattern ´

    originating from the lattice mismatch between Bi2Se3 and FeSe is observed. Tunneling spectra

    reveal the spatially inhomogeneous electronic structure of the Bi2Se3 thin films, which can be

    ascribed to the charge transfer at the interface.
