Ionic conductivity and dielectric relaxation in γ-irradiated TlGaTe2 crystals

γ-Radiation Stimulated Structural Transition of Monoclinic TlInS2 to Hexagonal Phase

“…Note that the position of "ðT Þ anomaly in the samples received up to 400 Mrad dose of -IR remains unchanged though decrease and broadening of this anomaly at phase transition become already considerable. 19) The doses of -IR larger than 1000 Mrad lead to qualitatively new structural changes in M-TIInS 2 . In fact, such changes can be noticed at an earlier stage of -IR as well.…”

“…¼ 1:23 MeV (Co 60 ) on the room temperature "ðT Þ and ðT Þ dependencies was already studied in some of the layered M-A 3 B 3 C 6 2 , including M-TlInS 2 . [16][17][18][19] However, the obtained experimental results were insufficient to built up a comprehensive and self-consistent picture of the influence of intrinsic defects on FPT in M-TlInS 2 .…”

“…Here we extend our experimental approach up to X-ray diffraction (XRD) and photoconductivity (PC) examinations, which, as well as "ðT Þ and ðT Þ measurements, have been carried out in a broader range of radiation fluencies in comparison with previous studies. [16][17][18][19] XRD and PC have been selected to monitor sample structure and shallow impurity states near the band gap, respectively.…”
