Abstract
We present a study of the transport measurements on lithium intercalated InSe single crystals. Lithium intercalant acts as a donor species and after intercalation the resistivity falls below 0.02 Ω cm with an increase in the carrier density. At low temperature pure InSe exhibits a two-dimensional conductivity owing to weak localization as a consequence of the weak disorder introduced by the large concentration of stacking faults. The logarithmic temperature dependence is found to be general and the classical formalism of the weak localization is applied. Upon intercalation the presence of Li atoms destroys the electronic interference waves and the weak localization disappears completely. The change in the electrical properties is discussed and an electronic band model is proposed.
