ZnS nanostructures for field emitters

We report new novel ZnS nanostructures show superior field emission with a low turn-on field, high field-enhancement factor, large current density and high stability indicating the capability of the ZnS branched architecture as field emitters. This excellent field-emission property is attributed to its high crystallinity, single-phased and cone-shaped nanometer-sized tips. This study suggests that optimized FE properties could be achievable through designing nanostructured architectures with a crystallographic orientation relationship.
