Abstract From structural analysis we have shown in a previous investigation that the series TlBa2Ca n Cu n+1O2n+5 and Tl2Ba2Ca n Cu n+1O2n+6 are composed of superconductor-semiconductor arrays. In this paper, we demonstrate that the unit cell of the Tl2Ba2Ca n Cu n+1O2n+6 series can further be viewed as composed of a composite block of superconductor-metal-semiconductor, where TlBa2CuO5 is the fundamental superconductor, TlO the metallic unit, and CaCuO2 the semiconductor block. It is indicated that theT c of Tl(2201) can be deduced from that of Tl(1201) based on Kresin's model of composite systems.
