Fermi surface topology and low-lying quasiparticle dynamics of parent Fe${}_{1+x}$Te/Se Superconductor by orbital-polarization resolved ARPES

Y. Xia, D. Qian, L. Wray +5

We report the first photoemission study of Fe${}_{1+x}$Te - the host compound of the newly discovered iron-chalcogenide superconductors (maximum T${}_c$ $\sim$ 27K). Our results reveal…
