abstract = "Ex situ analyses on topological insulator films require protection
against surface contamination during air exposure. This work
reports on a technique that combines deposition of protective
capping just after epitaxial growth and its mechanical removal
inside ultra-high vacuum systems. This method was applied to
Bi2Te3 films with thickness varying from 8 to 170 nm. Contrarily
to other methods, this technique does not require any sputtering
or thermal annealing setups installed inside the analyzing system
and preserves both film thickness and surface characteristics.
These results suggest that the technique presented here can be
expanded to other topological insulator materials.",
