Abstract : Thallium indium ditelluride single crystal, was prepared by aspecial design constructed by our group. A brass working chamberdesigned for measuring (TEP) in a wide range of temperature wasused. The experimental results indicates that T1InTe2 is of p-typeconductivity. The mobility of charge carriers, holes and electrons wasfound to be 2.129 × 103 cm2 / V, sec and 1.218 × 105 cm2 / V, secrespectively. The effective masses of the majority and minoritycarriers were deduced to be 5.367 × 10–37 kg and 6.856 × 10–43 kgrespectively. The diffusion coefficient, relaxation time and diffusionlength for holes was calculated to be 551.436 cm2 / sec, 7.142 × 10–21sec and 1.986 × 10–9 cm respectively. Also Dn . τn , Ln for the electronswas calculated to be 3.156 × 103 cm3 / sec, 5.222 × 10–26 sec and1.284 × 10–11 cm respectively. In addition to these pronouncedparameters, the efficiency of the thermoelectric element (figure ofmerit) was evaluated, which leads to better application in many fields .
