Synthesis, characterization of WS{sub 2} nanostructures by vapor phase deposition
Ultrathin two-dimensional WS{sub 2} nanostructures with various morphologies have been prepared on SiO{sub 2}/Si (300 nm) and sapphire substrates by vapor phase deposition method. Simultaneously, tungsten nanostructures have also been obtained during the growth process. The nanostructures and morpho...

| description | Ultrathin two-dimensional WS{sub 2} nanostructures with various morphologies have been prepared on SiO{sub 2}/Si (300 nm) and sapphire substrates by vapor phase deposition method. Simultaneously, tungsten nanostructures have also been obtained during the growth process. The nanostructures and morphologies of as-prepared products were systematically characterized by employing atomic force microscopy, Raman spectroscopy as well as scanning electron spectroscopy. The electrostatic properties of WS{sub 2} nanostructures were investigated exhibiting uniform surface potential and charge distributions. We have also detected the photoluminescence properties of WS{sub 2} nanostructures, which are dependent on the thickness and nanostructures of synthesized WS{sub 2}. These results suggest that the optoelectronic properties of WS{sub 2} nanostructures can be effectively tuned by quantum confinement effect and nanostructures. |
