- W2920341818 abstract "Abstract Atomically thin WS 2 nano-petals and nano-bristles were synthesized on vertically aligned carbon nanotubes (CNT) via magnetron sputtering at room temperature. The formation of the nano-petal morphology requires reaching a critical threshold in sputter deposition time, below which an amorphous film of WO 3 is obtained instead. Increasing the deposition time past a second threshold results in a change to the nano-bristle morphology. Both WS 2 nano-petals and nano-bristles were able to significantly enhance the electron emission of properties. The lowest turn-on voltage measured was to be 295 V and 355 V for the nano-petals and nano-bristles respectively, versus 425 V for pristine CNTs. The variation in the turn-on voltage is due to the electrical contacts at the interface between the different WS 2 structures, which induces current saturation at high emission currents. These results demonstrate that 2D WS 2 layers can be synthesized without the need for chemical routes and high growth temperatures if an appropriate template is employed." @default.
