Properties of PbS: Ni2+ Nanocrystals in Thin Films by Chemical Bath Deposition

Abstract: The growth of nanocrystalline PbS films by chemical bath deposition (CBD) onto glass at temperature T = 20 ± 2• C is presented in this research. We report on the modification of structural, optical, and electrical nanostructures due to in situ Ni-doping. The morphological changes of the layers were analyzed using SEM, AFM, and TEM. XRD spectra displayed peaks at 2θ = [26. 00, 30.07, 43.10, 51.00, 53.48], indicating growth on the zinc blende face. The grain size determined by X-rays diffraction of the undoped … Show more

“…Lead sulfide nanostructure was the one of it most promising alternative materials due to its unique [1,2]. Lead sulfide is unique promise material (p-type) characterized by a direct, narrow energy gap, very high carrier mobility, large Bore radius, higher constant dielectric, and very important absorbnce coefficient [3,4,5]. Additionally the size of nanostructure lead sulfide (PbS) reached less than the radius of Bohr quantum effects of electrons and holes occurred, this quantum effect leads to the creation of separate electronic states in the (CB) and (VB) of the hetrostructure compared with the density state of surface in the volumetric substance [6,7].…”
