We investigated transport properties under magnetic fields up to 8 T for FeSe 1 − x Te x thin films on CaF 2 . For x = 0.2 -- 0.4 , where T c ’s are the highest, resistive broadening was observed, while the width of superconducting transition was

Superconducting FeSe0.8Te0.2 thin films on SrTiO3, LaAlO3 and CaF2 substrates were electrochemically etched in an ionic liquid, DEME-TFSI, electrolyte with a gate bias of 5 V. Superconductivity at 38 K was observed on all substrates after the etching

We investigate superconducting properties of FeSe1−x1−xTex films with x=0−0.4,x=0−0.4, which are around the optimal Te contents, on CaF2 substrates. From the results of electrical resistivity measurements, the values of Tc in films with x=0.3

Iron chalcogenide superconductors FeSe1−xTe x are important materials for investigating the relation be-tween the superconductivity and the orbital and/or electronic nematic order, because the end member material FeSe exhibits a structural transiti
