“…It was already noticed above that Morgant et al [130,147], who studied phase diagram of thallium selenides using thermoanalytical, x-ray diffraction and metallographic examinations, reported on the observation of a new polymorphic cubic centered form of the solid TlSe at high temperature, around 470 K. The two forms, tetragonal α-form with a = 8.02 Å, c = 7.00 Å and cubic β-form with a = 6.187 Å, are separated by a two-phase (α + β) region near 470 K. The occurrence of the aforementioned β-form was confirmed by Romermann et al [148]. The expected properties of this phase were briefly discussed in section 6.…”

We present the first review of the current state of the literature on electronic properties and phase transitions in TlX and TlMX2 (M = Ga, In; X = Se, S, Te) compounds. These chalcogenides belong to a family of the low-dimensional semiconductors possessing chain or layered structure. They are of significant interest because of their highly anisotropic properties, semi- and photoconductivity, nonlinear effects in their I–V characteristics (including a region of negative differential resistance), switching and memory effects, second harmonic optical generation, relaxor behavior and potential applications for optoelectronic devices. We review the crystal structure of TlX and TlMX2 compounds, their transport properties under ambient conditions, experimental and theoretical studies of the electronic structure, transport properties and semiconductor–metal phase transitions under high pressure, and sequences of temperature-induced structural phase transitions with intermediate incommensurate states. The electronic nature of the ferroelectric phase transitions in the above-mentioned compounds, as well as relaxor behavior, nanodomains and possible occurrence of quantum dots in doped and irradiated crystals is discussed.

“…У даній системі існує 9 термічно стабільних сполук, існування яких достовірно підтверджено незалежно один від одного різними авторами. Серед них 3 бінарні: Tl2Se, TlSe плавляться конгруентно при 661 K та 603 K [2][3][4][5][6] відповідно, та Sb2Se3, з температурою конгруентного плавлення 863 K [7][8][9].…”

“…The chalcogenides compound formed from elements of group III and VI in the periodic table are very important due to their practical applications in different fields, such as electronic devices, refrigerating materials, photovoltaic detectors, and optical devices [1]. In the last few years, there has been great interest in the investigation of physical properties of layered ternary crystal with chemical formula TlMX 2 (M = Ga, In, X = Se, S, Te).…”

TlInS2 single crystal belonging to the group A 111 B 111 C v1 gets a great attention nowadays due to its electrical and optical properties, which make it a good candidate for photoconductivity applications. In the present study, the dependence of the AC-photoconductivity of TlInS2 single crystal on the chopping frequency was investigated by plotting (∆σ/∆σst − ω) versus the chopping frequency (15-300 Hz). The effect of different parameters including temperature (77-300 K), applied voltage (10-70 V), and light intensity (1000-7000 lx) on the dependence of AC-photoconductivity on the chopping frequency was studied. The results indicated that the AC-photoconductivity decreases with the increase in the chopping frequency regardless of the values of the effecting parameters (temperature, voltage, and light intensity). Due to its properties, TlInS2 single crystals represent a promising material for using in photodetector and radiation visualizer employed in recording information in optical devices. Moreover, these materials are suitable for solar batteries due to its ability to generate appreciable quantity of electrical power from sun radiation.
