Abstract
TlSbSe2 samples used for electrical measurements were cleaved from larger crystals grown by using the Bridgman-Stockbarger method. Electrical properties of TlSbSe2 have been carried out as a function of temperature (203-258 K) at different dc electric fields. The dc studies revealed the non-ohmic type of conduction (log I versus log V plot). The field lowering coefficientβ is evaluated from log I versus E1/2 plot. It is found that the dominant conduction mechanism in these samples is Poole-Frenkel type. The activation energies are also calculated at different voltages. It is seen that the activation energy decreases with increase of applied voltage.
