Perovskite - Wikipedia
The eponymous Perovskite CaTiO3 crystallizes in the Pbnm space group (No. 62) with lattice constants a = 5.39 Å, b = 5.45 Å and c = 7.65 Å.
Perovskites have a nearly cubic structure with the general formula ABO3. In this structure the A-site ion, in the center of the lattice, is usually an alkaline earth or rare-earth element. B-site ions, on the corners of the lattice, are 3d, 4d, and 5dWikipedia · Text under CC-BY-SA licenseStructural Properties of Perovskite - SpringerLink
The perovskite crystal lattice determines the reciprocal lattice configuration and consequently leads to a fixed energy band configuration in the momentum space.
