MACHINING NANOMETER-SIZED TIPS FROM MULTI-WALLED NANOTUBES

摘要

The invention provides sharpened multi-walled nanotubes and methods for sharpening multi-walled nanotubes. The methods of the invention use an electron beam to machine the multi-walled nanotube to the desired dimensions. The invention provides sharpened boron nitride nanotubes where the radius of the end of the sharpened tip is less than about 10 nm.
