Small structures showing field emission are of great importance for new electron sources, e. g. for flat panel displays. We present a novel method to produce regularly arranged uniform diamond field emitters exploiting gold nanoparticles as etching masks. Inverse diblock copolymer micelles loaded with gold salt are deposited onto boron doped (001)-oriented diamond substrates resulting in a hexagonally ordered monomicellar film. In a subsequent plasma step the polymer is removed and pure gold particles are obtained while maintaining the hexagonal order of the micellar array [1]. In a subsequent anisotropic etching step uniform diamond tips with a height of 45nm and a diameter of 10nm (FWHM) are prepared. Their emission properties are investigated using a standard diode setup as well as scanning tunnelling microscopy and spectroscopy.
