Query: Electronic and Structural Properties of a 4d-Perovskite: Cubic Phase of
  SrZrO$_3$   First-principles density functional calculations are performed within the
local density approximation to study the electronic properties of SrZrO$_3$, an
insulating 4d-perovskite, in its high-temperature cubic phase, above 1400 K, as
well as the generic 3d-perovskite SrTiO$_3$, which is also a d^0-insulator and
cubic above 105 K, for comparison reasons. The energy bands, density of states
and charge density distributions are obtained and a detailed comparison between
their band structures is presented. The results are discussed also in terms of
the existing data in the literature for both oxides.
