NOVELTY - The utility model claims an ultra-low work function material technology field, specifically claims an anode of super-low work function, comprising a single crystal silicon layer, HfO2 layer, single layer graphene, the additional layer; the upper surface of the single crystal silicon layer is attached with a layer of HfO2 layer, HfO2 layer on the surface with 5 asterisk 5 mm of single-layer graphene on the surface of the single-layer graphene layer is plated with a layer of additional layer, the single crystal silicon layer is a single crystal silicon layer with high doping, the thickness of the HfO2 layer is 20nm; the single-layer graphene is doped with static; the additional layer is cesium element or an oxygen element layers, the thickness of the additional layer is one atomic layer thickness. The utility model the anode work function is reduced to less than 3eV, which greatly improves the anode efficiency of energy conversion.
