ZnS hexagonal pyramids, consisting of zinc blende structured single crystals with a nanotip, are fabricated by a facile thermal evaporation method. Stable and strong UV emission at 337 nm and superior field emission with a low turn-on field, high field-enhancement factor, large current density, and small fluctuation are observed. The figure shows the growth mechanism of the ZnS pyramids.
