TlSbSe₂ samples used for electrical measurements were cleaved from larger crystals grown by using the Bridgman - Stockbarger method. Electrical properties of the samples are investigated with a view of determining the dominant conduction mechanism. The DC conduction studies revealed the non-ohmic type conduction. The activation energies are also calculated. It is seen that the activation energy decreases with increase of applied voltage.
