Abstract

A novel nanostructure of ultrathin Ge nanobelts bonded with nanotubes has been fabricated and characterized. Nanotubes (either carbon or BN) are first coated with amorphous germanium and then heated and observed by an in-situ TEM. The thickness, down to 2 nm, and the width of the Ge nanobelts are determined by the thickness of this amorphous Ge coating and the diameter of nanotubes, respectively.
