Abstract
We report on the electrical properties of chemically deposited PbSe films with controlled microstructure ranging from nanocrystalline to single crystal films. Control over the deposition mechanism consequently allowed control over the physical properties of the obtained films. The electrical conductivity, carrier concentration, drift mobility and carrier scattering mechanism were correlated with the film morphology. In polycrystalline PbSe films, the activation energy of the electrical conductivity is governed by the nature of the grain boundaries. In monocrystalline PbSe films, conductivity vs. temperature depends on carrier scattering from lattice vibrations.
