Study of HgBa${}_2$CuO${}_{4+\delta }$ by Angle-Resolved Photoemission Spectroscopy

W. S. Lee, T. Yoshida, W. Meevasana +10

We present the first angle-resolved photoemission measurement on the single-layer Hg-based cuprate, HgBa${}_2$CuO${}_{4+\delta }$ (Hg1201). A quasi-particle peak in the spectrum and a kink i…
