Behavior of the Switching Effect in P-Type TlInS2 Ternary Chalcogenide Semiconductor

Abstract. Investigation of the switching phenomenon in single crystal TlInS2 revealed that it is typical for a memory switch. The switching process takes place with both polarities on the crystal and have symmetrical shapes. Current-voltage characteristics (CVC) of symmetrical Ag/p-TlInS2/Ag structures exhibit two distinct regions, high resistance OFF state and low-resistance ON state having negative differential resistance (NDR). TlInS2 is a ternary semiconductor exhibiting S-type i-v characteristics. The results strongly indicate that the phenomenon in our sample is very sensitive to temperature, light intensity and sample thickness. The switching parameters were checked under the influence of different factors of the ambient condition
