The pressure effect on the resistivity and superconducting T c of prestrained thin films of the iron chalcogenide superconductor FeSe 0.5Te 0.5 is studied. Films with different anion heights above the Fe layer showing different values of ambient pressure T c's are compressed up to a pressure of 1.7 GPa. All films exhibit a significant increase of T c with pressure. The results cannot solely be explained by a pressure-induced decrease of the anion height but other parameters have to be considered to explain the data for all films.
