On the ferroelectric phase transition in polytypes of β-TlInS2 crystals
Permittivity measurements and x-ray diffraction study were performed for polytypes c and 2 c of β-TlInS 2 crystals in the temperature range T = 160–250 K. Substantial differences are revealed in the temperature, sequence, and character of the structural phase transitions associated with the formatio...

| Zusammenfassung: | Permittivity measurements and x-ray diffraction study were performed for polytypes
c
and 2
c
of β-TlInS
2
crystals in the temperature range
T
= 160–250 K. Substantial differences are revealed in the temperature, sequence, and character of the structural phase transitions associated with the formation of incommensurate modulated structures and the occurrence of a ferroelectric state in these polytypes. |
