We studied the defects of Bi2Se3 generated from Bridgman growth of stoichiometric and nonstoichiometric self-fluxes. Growth habit, lattice size, and transport properties are strongly affected by the types of defects generated. Major defect types of the BiSe antisite and partial Bi2-layer intercalation are identified through combined studies of direct atomic-scale imaging with scanning transmission electron microscopy in conjunction with energy-dispersive x-ray spectroscopy, x-ray diffraction…

The role of interstitial native defects in the topological insulator Bi2Se3
Results indicate that interstitial Bi atoms in octahedral sites between two consecutive quintuple layers have a lower formation energy than selenium vacancies and that these interstitials could act as a possible source of free electron carriers.
Interstitial defects in the van der Waals gap of Bi2Se3.
The defect structure of Bi2Se3 is studied with a combination of techniques, showing interstitial defects with mainly Bi character in an octahedral coordination in the van der Waals gap, independent of the applied sample preparation method (focused ion beam milling or cryo-crushing).
