In-plane optical spectroscopy study on FeSe epitaxial thin film grown on SrTiO${}_3$ substrate

R. H. Yuan, W. D. Kong, L. Yan +2

We perform in-plane optical spectroscopy measurement on (00l) FeSe thin-film grown on SrTiO${}_3$ substrate by pulsed laser deposition method. The study indicates that the low freque…
