The coherent {\it d}-wave superconducting gap in underdoped La${}_{2-x}$Sr${}_x$CuO${}_4$ as studied by angle-resolved photoemission

M. Shi, J. Chang, S. Pailhés +12

We present angle-resolved photoemission spectroscopy (ARPES) data on moderately underdoped La${}_{1.855}$Sr${}_{0.145}$CuO${}_4$ at temperatures below and above the superconducting trans…
