“…In previous studies , the temperature dependence of the permittivity and the с unit cell parameter were determined for C ‐ and 2 C ‐polytypes in both TlInS 2 and TlGaSe 2 (isostructural analog of TlInS 2 ) crystals. The differences in the character of the temperature dependencies for these two polytypes were revealed.…”

The influence of the X‐ray irradiation on the crystal structure of TlInS2 C and 2C polytypes were studied by single‐crystal X‐ray diffraction method. The scanning of the reciprocal space in the planes (0kl)*, (h0l)*, (hhl)* were carried out for initial and irradiated samples (absorbed doses are 0.9 and 2.9 kGy) in the temperature range 180–300 K. It was found that after irradiation, the incommensurate phase satellites q(−δ, 0, +0.25) and q(+δ, 0, −0.25) (δ = 0.04) were observed even at room temperature in the C‐TlInS2 samples. Their intensities vary in direct proportion to the dose and significantly differ from each other. The 10 h annealing at 430 K completely destroyed these incommensurate structures. The temperature dependences of the incommensurate and commensurate phases volume fractions were obtained for unirradiated, irradiated, and annealed C‐TlInS2 samples. The modulation satellites of the incommensurate and commensurate phases were not observed in the temperature range of 180–300 K in the irradiated as well as unirradiated samples of the 2C‐polytype TlInS2. The role of defect density waves in the formation of the modulated structures in the irradiated TlInS2 crystals is discussed.

“…The experimental results for the unirradiated samples were presented in our recent publication [16]. In particular, the appearance of the satellites with wave vector q(Çd, 0, AE0.25) (d ¼ 0.04) near l ¼ 2n þ 1 the reciprocal lattice sites at a temperature 238-240 K in plane (h0l) Ã was observed.…”
