Conduction mechanisms in TlSbSe₂ chalcogenides

Abstract

TlSbSe 2 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. DC conduction studies reveal that Poole -Frenkel conduction is predominant. 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.

“…This compound is a layered crystal that belongs to the monoclinic system, with the space group P2 1 (C 2 2 ) and lattice parameters a = 9.137 Å , b = 4.097 Å , c = 12.765 Å , b = 111.75° [12]. Although some of the structural, optical and electrical properties of TlSbSe 2 have been studied previously [11][12][13][14][15][16][17][18][19][20][21][22][23].…”
