Abstract：

In　this　work,　we　demonstrated　the　field　emission　properties　of　few　layer　molybdenum　disulphide　(MoS　2　)　nanosheets　synthesized　by　a　hydrothermal　method.　Structural　investigation　indicates　the　as-synthesized　MoS　2　layers　were　two　dimensional　few　layer　nanosheets　with　a　sharp　atomic　edges.　The　field　emission　properties　of　the　MoS　2　nanosheets　were　investigated　and　the　results　indicate　that　the　MoS　2　nanosheets　had　an　excellent　field　emission　performance　with　turn　on　field　of　1.0 V/μm,　threshold　field　of　2.1 V/μm,　and　a　field　enhancement　factor　of　9880.　Furthermore,　the　emission　current　shows　the　stability　over　2 h　of　continuous　operation.　The　as-synthesized　MoS　2　few　layer　nanosheets　hold　potential　for　application　in　next-generation　field　emission　devices.　©　2016　Elsevier　B.V.
