Popis: | The dispersion relation of the single hole in the $CuO_2$ plane is calculated in the self-consistent Born approximation for the three-band Hamiltonian. We find that direct oxygen-oxygen hopping removes the strong anisotropy of the hole spectrum around the band minima. Our results compare well with recent photoemission measurements of the single-hole dispersion relation in $Sr_2 CuO_2 Cl_2$. 9 pages, RevTex, 4 postscript figures in one ps-file, Latex file and figures have been uuencoded; to appear in Phys.Rev.B |
