Measurement of an Anisotropic Energy Gap in Single Plane Bi_2Sr_(2-x)La_xCuO_(6+d)

Jeffrey M. Harris, P. J. White, Z. -X. Shen +8

We report angle-resolved photoemission spectra both above and below T_c in the single-plane cuprate superconductor Bi_2Sr_{2-x}La_xCuO_{6+d}. The superconducting state measurements…
