The resistivity, ρ(T), of Cu2ZnSnS4 powder samples, obtained by a solid-state reaction method from pure elements, exhibits an activated character. The Mott variable-range hopping charge transfer is observed between T ∼100–230 K, followed by the conductivity due to activation of holes into the states above the mobility threshold when T is increased. Such behavior, accompanied by semi-width W of the...
Cu2ZnSnS4 thin films have been produced via rapid thermal evaporation of off-stoichiometric kesterite powder followed by annealing in an Ar atmosphere. Different heating rates were applied during the thermal treatments. The chemical composition and structural properties of the deposited layers as well as the distribution of the elements through the kesterite thin film have been investigated. The initial...
