Abstract
The temperature dependence of TlInSе2 monocrystal’s volt-ampere characteristics, photoconductivity and electroconductivity has been studied. It has been established that the current flow mechanism in TlInS2 monocrystal with a tetragonal modification is connected with the space charges at E<102V/cm fields and the field effects at E >102V/cm values of the field. It has been shown that the photocurrent switches off at 180 K temperature at the expense of recharging of r-centers when TlInS2 monocrystal is illuminated by white light.
