Thallium Selenide single crystals were prepared by a special design using Bridgmantechnique constructed by the authors. An investigation was made on the influence of temperature on the electrical conductivity and Hall effect in two crystallographic directions. The anisotropic properties were checked, and the anisotropic factor was observed to increase with temperature decrease. The energy gap as well as the ionization energy was calculated. The conductivity throughout the entire temperature range was found to be of p‐type. The Hall mobilities derived from these measurements at room temperature were of the order μH ⟂ = 42.66 cm 2 /vs and μH ∥ = 112.2 cm 2 /vs.
