Anisotropy of hopping conductivity in TIGaSe2, crystal

Full Text: The temperature dependences of electrical conductivity of a chained semiconductor crystal TIGaTe2 in a direction of chains and perpendicularly have been investigated. It was established that in a constant electrical field in both crystallographic directions took place hopping conductivity with variable length of a jump on located near Fermi level. The energy activation of conductivity has been determined. It was appreciated density of a condition in a vicinity of a Fermi level, their disorder, radius of localization, average distance of jumps of carriers
