Characterization of MnS films deposited by the spray pyrolysis method

Abstract

Polycrystalline MnS film samples were deposited by the spray pyrolysis method onto glass substrates held at 300 °C, using aqueous precursor solutions of MnCl2 and (SC(NH2))2 and compressed air as a carrier gas. Electrical resistivity of the MnS films measured by the direct current four-probe technique showed strong correlations with film grain parameters such as grain boundary energy and grain size. The effects of annealing time on dislocation density, microstrain, grain size and grain boundary energy are discussed.
