A simple route to carbon micro- and nanorod hybrid structures by physical vapour deposition
Tilted well-aligned carbon micro- and nano-hybrid rods were synthesized on Si at different substrate temperatures and incident angles of carbon source beam using the hot filament physical vapour deposition technique. The morphologic surfaces, chemical compositions and bond structures of the oblique carbon rod-like structures were investigated by scanning electron microscopy, field emission scanning electron microscopy, transmission electron diffraction and Raman scattering spectroscopy. The field emission behaviour of the fabricated samples was also measured.
