The high-temperature superconduct?or, HgBa 2 CuO 4؉ ( '0), is the 5rst and arguably the most simple member of the homologous series of mercury-based cuprates, of general formula HgBa 2 Ca n؊1 Cu n O 2n؉2؉ (n ؍ 1. . . 8). The presence of interstitial oxygen in the HgO rock salt layer is crucial in
Local density approximation calculations of the electronic structure of HgBa2C'uO4 arc reported along with a number of properties identifiable from it. For the stoichiometric material, the only band crossing the Fermi energy is the Cu-O derived anlibonding state characteristic of high-7;, cuprates:
