An Efficient Route to Graphitic Carbon-Layer-Coated Gallium Nitride Nanorods

The coating of gallium nitride nanorods with graphitic carbon layers via conventional chemical vapor deposition is reported. The outer graphitic shells are generally composed of 1–5 layers, encapsulating GaN nanorods of diameter 5–60 nm and lengths of up to 30 μm (see Figure). These chemically inert protection layers conform to the shape of the nanorod edges, whether straight or saw-like.
