Fate of $yz$/$zx$ orbital degeneracy and $xy$ Fermi surface in Ru substituted FeSe${}_{1-x}$Te${}_x$

T. Sugimoto, D. Ootsuki, K. Sawada +14

We have investigated the impact of Ru substitution on the multi-band electronic structure of FeSe${}_{1-x}$Te${}_x$ by means of angle-resolved photoemission spectroscopy (ARPES). The A…
