TL;DR: In this paper, the crystal structures and superconducting properties of thin films of FeSe$0.5}$Te$ 0.5$ grown on eight different substrates were investigated.

TL;DR: In this paper, the crystal structures and superconducting properties of thin films of FeSe0.5Te 0.5 grown on eight different substrates were investigated, and it was shown that the presence or absence of an amorphous-like layer at the substrate surface plays a key role in determining the structural and superconding properties.

TL;DR: In this article, the in-situ epitaxial growth of FeSe0.5Te 0.5 thin films is demonstrated on a nonoxide substrate CaF2.

TL;DR: In-situ epitaxial growth of FeSe$0.5}$Te$ 0.5$ thin films is demonstrated on a non-oxide substrate CaF$_2$ in this article.

TL;DR: In this paper, superconducting NdFeAs(O,F) thin films were grown on GaAs substrates by molecular beam epitaxy, and they were shown to exhibit a clear super-conducting transition with an onset temperature up to 48 K and zero resistance temperature of up to 42 K without the need of an ex situ annealing process.
