Evidence for a second one-dimensional set of states shedding light on the normal phase of high-Tc superconductors. Saini, N., Avila, J., Asensio, M., Tajima, S., Gu, G., Koshizuka, N., Lanzara, A., & Bianconi, A. Physical Review B, 57(18):R11101–R11104, 1998. Paper doi abstract bibtex We have identified a set of electronic states with a one-dimensional dispersion in the Î ” =(0,0) to M 1 =( Ï€ ,0) direction crossing the Fermi surface at one point k F =0.2±0.03 Ï€ by angle-resolved photoemission. The one-dimensional character of these electronic states is demonstrated by missing dispersion along the orthogonal direction, observed in energy-distribution curves, and by k -space mapping of the Fermi surface, using angle scanning photoemission. The observed electronic states beyond the well-known large Fermi surface provoke the models based on charge and spin ordering in the CuO 2 plane of high- T c superconductors.
