摘要： A method of fabricating high resolution atomic force microscopy (AFM) tips including a single semiconductor nanowire grown at an apex of a semiconductor pyramid of each AFM tip is provided. The semiconductor nanowire that is grown has a controllable diameter and a high aspect ratio, without significant tapering from the tip of the semiconductor nanowire to its base. The method includes providing an AFM probe including a semiconductor cantilever having a semiconductor pyramid extending upward from a surface of said semiconductor cantilever. The semiconductor pyramid has an apex. A patterned oxide layer is formed on the AFM probe. The patterned oxide layer has an opening that exposes the apex of the semiconductor pyramid. A single semiconductor nanowire is grown on the exposed apex of the semiconductor pyramid utilizing a non-oxidized Al seed material as a catalyst for nanowire growth.
