Relationships between Superconductivity and Nematicity in FeSe${}_{1-x}$Te${}_x$ ($x=0-0.5$) Films Studied by Complex Conductivity Measurements

H. Kurokawa, S. Nakamura, J. Zhao +7

We measured the complex conductivity, $\sigma$, of FeSe${}_{1-x}$Te${}_x$ ($x=0-0.5$) films in the superconducting state which show a drastic increase of the superconducting transition temp…
