Facile growth of horizontally suspended carbon nanotubes

Facile growth of horizontally suspended carbon nanotubes

This paper reports a facile method to grow horizontally suspended carbon nanotubes (CNTs) spanning across wide trenches. The vertical thickness of resultant CNT mats was controlled by adjusting the deposition direction of catalysts relative to the top surface of the substrate. The Raman spectroscopy...
