Abstract
PbS particles of average diameters ranging from 9.9 to 18.0 nm have been synthesized within a polyacrylamide matrix. The percolative chains of these particles exhibit intrinsic semiconducting behavior at temperatures higher than 340 K. The estimated band gap for these particles are found to be much higher than that of bulk PbS being in the range 1.03 to 1.49 eV. The low-temperature conductivity of these composites appears to be controlled by an electron tunneling mechanism.
