Abstract

See full text

A nanotip, is fabricated by modifying a precursor nanotip having an apex and a shank by applying an electric field in the presence of a reactive gas to perform field-assisted etching wherein atoms are preferentially removed from the shank by chemical interaction with the reactive gas, and controlling the reactive gas pressure and/or tip voltage to vary the electric field so as to promote field evaporation of apex atoms during fabrication of the nanotip and thereby control the overall profile of the resulting nano-tip. The method permits shaping of the overall tip profile.
