The field emission performance of the rGO-Ag NW nanocomposite, rGO and Ag NW emitters was investigated. The turn on field required to draw an emission current density of similar to 1 mA cm(-2) was found to be similar to 5.00, 3.92 and 2.40 V mu m(-1) for the Ag NW, rGO and rGO-Ag NW nanocomposite emitters, respectively. The combined contribution of the sharp edges of the thin graphene sheets and high aspect ratio of the Ag nanowires, and their synergetic effect in the rGO-Ag NW nanocomposite, are responsible for the enhanced field emission behavior. First-principles density functional calculations show that the enhanced field emission may also be due to the overlapping of the electronic structures of the Ag NWs and rGO nanosheets.</p>1 aSamantara, Aneeya, K.1 aMishra, Dillip, Kumar1 aSuryawanshi, Sachin, R.1 aMore, Mahendra, A.1 aThapa, Ranjit1 aLate, Dattatray, J.1 aJena, Bikash, Kumar1 aRout, Chandra, Sekhar  uhttps://library.ncl.res.in/content/facile-synthesis-ag-nanowire-rgo-composites-and-their-promising-field-emission-performance-0
