Preparations and characterizations of polycrystalline PbSe thin films by a thermal reduction method

Investigation on structural, optical, morphological and electrical properties of thermally deposited lead selenide (PbSe) nanocrystalline thin films

“…Various techniques such as photochemical [13,14], sonochemical [15], vacuum thermal evaporation [16][17][18], successive ionic layer adsorption and reaction (SILAR) [19], electrodeposition [20] and chemical bath deposition [21][22][23] have been adopted for the preparation of PbSe thin films. Among these methods, thermal evaporation imparts some feasible device based qualities like optimum stoichiometry, morphology and crystalline alignment to the films, which are the key factors deciding the performance of the films for their suitability in developing special devices.…”

“…Among these methods, thermal evaporation imparts some feasible device based qualities like optimum stoichiometry, morphology and crystalline alignment to the films, which are the key factors deciding the performance of the films for their suitability in developing special devices. However, limited reports [16][17][18] are available for the preparation of PbSe thin films by thermal evaporation technique using the commercially available PbSe powders. To the best of our knowledge, no attempt has been made to grow PbSe films by thermal evaporation method using chemically synthesized PbSe nanocrystalline powders.…”

Synthesis and characterization of nanoparticle thin films of a-(PbSe)100−xCdx lead chalcogenides

“…There are also few reports on PbSe films and PbSe nanostructured thin films deposited by thermal evaporation technique [23-26]. Ma et al [27] deposited polycrystalline PbSe thin films on Si substrates by thermal reduction method with carbon as the reducing agent. Kumar et al [28] have studied the electrical, optical, and structural properties of PbSe 1− x Te x thin films prepared by vacuum evaporation technique.…”

Optical and photoconductive properties of Pb0.9Sn0.1Se nano-structured thin films deposited by thermal vacuum evaporation and pulsed laser deposition

“…Deposition technique of chalcogenide materials was found recently controlling the deposited film properties. Many reports in lead selenide and its ternary compounds were deposited by chemical solution growth techniques [16][17][18][19][20][21], molecular beam epitaxy, MBE [22][23][24][25], electrochemical deposition [26], sol-gel technique [27], thermal evaporation [28,29], thermal reduction method [30], hydrothermal synthesis [31] and colloidal solution [32]. Each technique treats a specific problem such nano architecting, nano devices, wide area, ease preparation, nano particles and colloide, respectively.…”
