Abstract:
The temperature dependence of the electrical conductivity of chain-layered $p$-TlInSe$_2$ single crystals grown in the temperature range 120–290 K has been studied. The temperature dependence of the electrical conductivity of $p$-TlInSe$_2$ single crystals plotted on a semilogarithmic scale was found to be nonlinear. In the temperature range starting from 120 K to 200 K, the electrical conductivity of crystals shows one rectilinear section with one slope, and when the temperature rises above 200 K, it shows the second rectilinear section with another slope. In the studied temperature range, the conductivity of $p$-TlInSe$_2$ crystals is most likely of the usual activation character, with acceptor activation energies of $0.196$ and $0.445$ eV.
Keywords:electrical conductivity, single crystal, activation energy, thermoacceptors.
