A “patterned-seeding technique” in combination with a “nanodiamond masked reactive ionetching process”is demonstrated for fabricating vertically aligned diamond-graphite hybrid (DGH)nanorod arrays.The DGH nanorodarrays possess superior field electron emission (FEE) behavior with a low turn-on field,long lifetime stability, and large field enhancement factor. Such an enhanced FEE isattributed to the nanocomposite nature of the DGH nanorods, which containsp2-graphitic phases in the boundaries of nano-sizeddiamondgrains. The simplicity in the nanorod fabrication process renders the DGH nanorods of greater potentialfor the applications as cathodes in field emission displays and microplasma displaydevices
