Abstract
Measurements of the electrical conductivity and Hall effect were carried out in a wide temperature range (200-500Â K) for Ga2Te3 crystals. The crystals were grown in single crystalline form by making a modification of the travelling heater method technique. The measurements revealed unusual observations in the electric conductivity and Hall mobility indicating the presence of some type of phase transitions at about 430Â K. So, ferroelectric behavior was examined for confirming the presence of second-order (ferroelectric) phase transition. An energy gap of 1.21Â eV and depth of the impurity center of 0.11Â eV were found.
