Abstract
We present here the complete results of tight-binding calculations of the band structures and Fermi surfaces for the TlBa2Can-1CunO2n+3 and Tl2Ba2Can-1CunO2n+4 (n=1, 2, and 3) superconducting phases. We show the density of states (partial and total) and three-dimensional Fermi surfaces for each of these six phases. The single-Tl-O-layer Fermi surfaces contain noncylindrical features, and the Fermi surfaces of Tl 2:2:2:3, Tl 1:2:0:1, Tl 1:2:1:2, and Tl 1:2:2:3 show pockets corresponding to Tl-O band crossings at EF.
