- •
Crystal symmetry decreases with CT concentration from cubic to hexagonal structure.
- •
Lattice constants as well as the ordered degree change with CT concentration.
- •
Ordered structures turn from 1:1 to 1:2 ordering with change of crystal structures.
- •
There is a correlation between FIR phonon modes and dielectric properties.
