• As we know that TWs formation takes place due to cubic to low symmetry structural phase transition ( due to either by cation displacement or octahedra rotation or both), which minimize the total strain of low symmetry phase. If i consider, phase transition only due to octahedra rotation or tilting, how the TWs will form in this type of structure ? i want to visualize Tws formation by rotating the octahedra of unit cell (which is responsible for structural phase transition as well)?
