Strong electron-phonon coupling in Hg1201

ORAL

Abstract

Among single-layer cuprate high temperature superconductors, some materials have maximum Tc (Tc, max) near 40K while others have Tc, max near 100K, and the origin of this discrepancy is still unsettled. We present doping-dependent angle-resolved photoemission spectroscopy (ARPES) studies on HgBa2CuO4+δ (Hg1201), a single-layer cuprate with higher Tc, max, with a focus on spectral features which differ from more commonly studied single layer cuprates with lower Tc, max. Our studies indicate two different aspects of enhanced electron-phonon coupling in this system with distinct momentum dependence.
