An electron emitting device characterized by a monocrystalline substrate, a plurality of monocrystalline nanomesas or pillars disposed on the substrate in a spaced relationship and extending generally normally therefrom, monocrystalline self-assembled tips disposed on top of the nanomesas, and essentially atomically sharp apexes on the tips for field emitting electrons. A method for making the emitters is characterized by forming a gate electrode and gate electrode apertures before forming the tips on the nanomesas. |
