A field emission device comprises a substrate (110), a buffer layer (120) arranged on the substrate (110), an emitter layer (130) and a collector layer (140) respectively arranged on two ends of the buffer layer (120), and metal electrode layers (151) and (152) respectively arranged on the emitter layer (130) and the collector layer (140). A channel (160) is provided between the emitter layer (130) and the collector layer (140). A method for preparing the field emission device. With the field emission device and the preparation method, the field enhancement factor can be improved, and the field emission performance can be improved. |
