| dc.description | Angular dependence of gap, seen in photoemission, its evolution with doping and temperature are interpreted on base t-t'-U Hubbard model in which a pseudogap is a working function for electrons removing from dielectric segments of zone boundary. Tunnel spectra in one-particle approximation display only superconducting gap and too large asymmetry in regions aside from optimal doping. Spectral functions confirm sharp well defined Fermi boundary at $k_x=k_y$ direction and smoothed destructed one at the $\G(0,0)-M(π,0)-Y(π,π)$ path. Both tunnel and ARPES data seem require spreading a model to bilayer ones. | |
