Among all the Iron based superconductors (IBS) families the iron chalcogenides FeSexTe1-x, also called 11 phases, are the simplest, and they are quite attractive because of their relatively ease of fabrication and the absence of toxic arsenic. 11 thin films have been successfully grown on single crystalline substrates and on technical metallic...

In this paper, the feasibility of producing Fe(Se,Te)-coated conductors on cost-effective, unbuffered Invar 36 substrates is studied. A suitable substrate with a sharp 001<100> texture and a misorientation angle lower than 10° was developed, and the possibility of growing epitaxial thin films without any buffer layer was demonstrated. It was...
