摘要
Permittivity measurements and x-ray diffraction study were performed for polytypes c and 2c of beta-TlInS2 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.
