Abstract
Heat capacity, lattice parameter, spectral and temperature dependences of photoconductivity of chained crystal Tl In Se2 have been investigated in this work. For the first time, it has been found that the phase transtion takes plase at temperatures 135 and 184 K in this crystal. The changes of heat capacity, photoconductivity and lattice parameter of Tl In Se2 in the region of phase transition is supposed to be connected with the presence of an incommensurate phase in this crystal.
