Abstract

A MoS₂@VS₂micro-nanocomposite was synthesizedviaa two-step hydrothermal method. The field emission properties of the MoS₂@VS₂micro-nanocomposite were investigated for the first time. The finger-like VS₂has a larger field-enhancement factor than the common sheet-like morphology. Besides, MoS₂composited with VS₂not only improves the stability, but also improves the field emission performance of the sample greatly. Compared with pure MoS₂and VS₂, the MoS₂@VS₂composite sample has the best field emission performance, including low turn on (0.8 V μm⁻¹) and threshold fields (1.6 V μm⁻¹), small work function, large field-enhancement factor, and good current stability. We attribute the enhanced field emission performance to the synergy of the two materials. We believed that the MoS₂@VS₂micro-nanomaterial reported in this work might be one of the best candidates for flat panel display materials.
