摘要：

We report on the fabrication of Fe-Te-S epitaxial thin films on SrTiO(3)(100) and MgO(100) single crystal substrates by pulsed laser deposition. Crystal structure was checked by X-ray diffraction, composition by scanning electron microscopy and energy dispersive spectroscopy (SEM-EDS), and superconductivity by resistance measurements. All the films deposited in the temperature range 300-400 degrees C were grown epitaxially on both substrates with a 4-fold symmetry. A zero resistance condition was not reached, but even if the films present a stoichiometric excess of Fe there is a clear upturn at 6 K. (C) 2009 The Japan Society of Applied Physics
