abstract = {The atomic structure of topological insulators Bi2Te3 thin
films on Si (111) substrates grown in van der Waals mode by
molecular beam epitaxy has been investigated by in situ
scanning tunneling microscopy and scanning transmission
electron microscopy. Besides single and multiple quintuple
layer (QL) steps, which are typical for the step-flow mode
of growth, a number of 0.4 QL steps is observed. We
determine that these steps originate from single steps at
the substrate surface causing domain boundaries in the
Bi2Te3 film. Due to the peculiar structure of these domain
boundaries the domains are stable and penetrate throughout
the entire film.},
