Weak ferroelectricity in layered A3B3C26 ferroelectric-semiconductor materials
Allakhverdiev K. R., Salaev F. M., Mikailov F. A., Mamedov T. S.
A phase transition to a phase which has a weak ferroelectricity has been observed for the first time in layered TlInS2 and TlGaSe2 ferroelectric-semiconductor materials. The detected phase transition is assumed to be an isomorphic phase transition.
