Though already known since the year 1912, reliable structural data of the semimetallic phase TlTe down and below the reported phase-transition temperature of 170 K were still lacking. To 5ll this gap, we performed low-temperature X-ray di4raction investigations on single crystals of TlTe down to 135
Measurements of the dielectric properties of Sn 2 P 2 S 2X4 Se 3X6 crystals at submillimeter wavelengths indicate that there are two structural phase transitions of incommensurateยฑferroelectric and para-electricยฑincommensurate in this material at temperatures T C 224 K and at about T i 230 K.
