Author(s): E. Razzoli, G. Drachuck, A. Keren, M. Radovic, N. C. Plumb, J. Chang, Y.-B. Huang, H. Ding, J. Mesot, and M. Shi Using angle-resolved photoemission spectroscopy (ARPES), it is revealed that the low-energy electronic excitation spectra of highly underdoped superconducting and nonsuperconducting La 2- x Sr x CuO 4 cuprates are gapped along the entire underlying Fermi surface at low temperatures. We show how the gap fu... [Phys. Rev. Lett. 110, 047004] Published Fri Jan 25, 2013
