Perovskite has a rhombohedral structure (or hexagonal) with formula ABO3, while belonging to the space group of R3c (number #161). They are popular in applications of functional devices, exhibiting ...
The general formula for a perovskite is ABO3 where A and B are cations. The easiest way to visualize the structure is in terms of the BO6 octahedra which share corners infinitely in all 3 dimensions, ...
