Abstract

We present electronic band structure of Ag $_{5}$ Pb $_{2}$ O $_{6}$ with layered hexagonal structure containing one-dimensional chains and two-dimensional Kagomé layers of silver. A half-filled conduction band shows extremely simple, single nearly-free-electron-like Fermi surface. The conduction band is composed of an antibonding state of Pb- $6 s$ and O- $2 p$ mixing with Ag-4d and $5 s$ . Mass enhancement in the state density at the Fermi energy is expected to be negligibly small by comparing with the specific-heat data. Calculated Fermi velocity is consistent with small anisotropy observed in transport properties. Doping effects on the electronic structure are also discussed.
