“…It was interesting to observe that SbTeI pellet shows significant decrease in the resistance when pressed between two plates; that is, resistance was found to decreased from 100's of ohms to as low as This indicates the piezoelectric property of SbTeI. As the material belongs to SbSI family and SbSI is already confirmed to be a piezoelectric material [8], there is a strong possibility that SbTeI is also a piezoelectric material.…”

“…Nitsche and Merz [7] have synthesized materials like SbSI, SbSBr, SbSeBr, SbSeI, SbTeI, BiSCl, BiSBr, BiSI, BiSeCl, and BiSeBr and studied their photoconducting properties. Papazoglou and Rentzeperis [8] have examined in detail the crystal structure of SbTeI and also reported that SbSI has metallic and semiconducting behavior. Kichambare et al [9][10][11] prepared SbTeI at different temperatures and calculated the values of lattice constants, ionization potentials, and activation energies.…”

“…Since in-depth studies on the electrical properties of SbTeI are not made [3][4][5][6][8][9][10][11][12], it was thought to be desirable to study the electrical properties of SbTeI to find out the carrier concentration, mobility, piezoelectric property, capacitance, and so forth. In this paper, we report synthesis of SbTeI using solid state reaction technique and electrical properties studies using van der Pauw and two probe techniques in the temperature range of 4 K-550 K.…”

Needle shaped SbTeI crystals were obtained by solid state reaction. Electrical resistance was measured in the temperature range of 4 K to 550 K. SbTeI shows a metallic behavior from 4 K to 300 K, and at higher temperature (>300 K), it shows semiconducting behavior. Unlike SbSI, this material shows almost zero resistance around 550 K. It shows a piezoelectric behavior with a capacitance of 717 pF and its carrier density and nobilities are found to be 2.12 × 1016 cm−3 and 1.01 cm2/(V·s), respectively. Crystals of SbTeI are characterized by XRD, SEM, and Raman analysis. Electrical activation energy is found to be 0.52 eV. It is suggested that this material may be studied for its application as a superconductor with Tc higher than room temperature.

“…SbTeI melts peritectically by decomposition at 645 K and crystallizes in a monoclinic structure: a=13.701, b=4.2418, c= 9.201 Å, β=128.63 0 (F.gr. C2/m) [15,16]. The complete phase diagram of the Sb-Te-I system was constructed and the thermodynamic properties of the SbTeI compound were studied [17].…”

The SbTeI−Bi 2 Te 3 polythermal section of the phase diagram of the Sb 2 Te 3 +2BiI 3 ↔Bi 2 Te 3 +2SbI 3 reciprocal system was constructed using DTA and XRD methods. It was established that Bi 2-x Sb x Te 3 solid solutions (α-phase) primarily crystallize from the liquid phase along this section. Subsequently, crystallization proceeds by a number of non-and monovariant reactions, α+γ 1 , α+γ 2 , and α+γ 1 +γ 2 (γ 1 and γ 2 are solid solutions based on SbTeI, and BiTeI) heterogeneous regions of are formed in subsolidus.

“…It crystallizes in the monoclinic space group C2/m with the unit cell parameters a = 13.701, b = 4.2418, c = 9.201 Å, b = 128.638 [4]. Its crystal structure represents a unique monoclinic variation of the SbSI structure type [5], in which typical for these structures (SbTe) double chains run along the b axis and alternate with the iodine atoms in the ac plane.…”

Phase diagram of the Sb-Te-I system and thermodynamic properties of SbTeIThe Sb -Te -I system was investigated by using differential thermal analysis, X-ray diffraction analysis and electromotive force measurements with an antimony electrode. A number of polythermal sections and the projection of the liquidus surface were constructed. The fields of the primary crystallization, as well as the types and coordinates of nonand monovariant equilibriums were determined. It is shown that the quasi-binary sections SbI 3 -Sb 2 Te 3 ,S b I 3 -Te, and SbI 3 -TeI 4 triangulate the Sb -Te -I system, leading to four independent subsystems. From the electromotive force measurements, the partial molar functions of antimony as well as the standard integral thermodynamic functions of SbTeI were calculated. The latter were found to have the following values: ÁG 0 f;298 = -55.77 ± 1.7 kJ · mol -1 ; ÁH 0 f;298 = -55.72 ± 1.39 kJ · mol -1 ; S 0 298 = 153.5 ± 2.8 J · K -1 ·mol -1 .
