About photoconductivity of TlInSe<sub>2</sub>
The current-voltage, lux-ampere characteristics and kinetics of relaxation of photoconductivity in single crystals of TlInSe2 have been investigated. Observed an anomalously large relaxation times τ « 10<sup>3</sup> s and other features of the photoconductivity are explained by barrier theory of inhomogeneous semiconductors. The driftbarrierheight of E<sub>dr</sub> ≈ 0.1 eV and recombination barrierheight of E<sub>r</sub> ≈ 0.45 eV have been determined.
