Superior Field Emission Properties of Layered WS2-RGO Nanocomposites
Open accessAbstract
We report here the field emission studies of a layered WS 2-RGO composite at the base pressure of ~1 × 10−8 mbar. The turn on field required to draw a field emission current density of 1 μA/cm 2 is found to be 3.5, 2.3 and 2 V/μm for WS 2, RGO and the WS 2-RGO composite respectively. The enhanced field emission behavior observed for the WS 2-RGO nanocomposite is attributed to a high field enhancement factor of 2978, which is associated with the surface protrusions of the single-to-few layer thick sheets of the nanocomposite. The highest current density of ~800 μA/cm 2 is drawn at an applied field of 4.1 V/μm from a few layers of the WS 2-RGO nanocomposite. Furthermore, first-principles density functional calculations suggest that the enhanced field emission may also be due to an overalp of the electronic structures of WS 2 and RGO, where graphene-like states are dumped in the region of the WS 2 fundamental gap.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
