Direct Deposition of Bamboo‐Like Carbon Nanotubes on Copper Substrates by Sulfur‐Assisted HFCVD
Journal of Nanomaterials, Volume 2008, Issue 1, 2008., 2008 Films of bamboo‐like carbon nanotubes (BCNTs) were grown directly on copper substrates by sulfur‐assisted hot filament chemical vapor deposition (HFCVD). The effects of substrate temperature and growth time over the BCNT structure were investigated.
