Abstract

The FeSexTe1-x has been proved to be a novel superconductivity with topological properties. Iron chalcogenide FeSexTe1-x attracted much attention because of its simple structure, which is favorable for probing the superconducting mechanism. The superconducting properties are significantly affected by different microstructures. In this work, FeSe0.5Te0.5 crystals with different structures including morphology, crystal structure, electronic structure, phonon mode, chemical states of the elements caused by different grinding techniques were grown. The structure related magnetism, transport properties, band structure, critical temperature, and critical current were studied. The Fe atoms contribute to the density of state around the Fermi level. The highest superconducting shielding volume fraction as well as the maximum critical current value existed in the sample having the minimum lattice parameter and highest Te element content deficiency.
