Low-temperature growth of carbon nanofibers by selective heating of catalyst

Vasenkov A.V., Kolobov V.V., Melechko A.V, CFD Research Corporation, US

A critical technological challenge for many potential carbon-nanotubes (CNT) and carbon nanofibers (CNF) applications is to have a process for a direct synthesis of aligned/micropatterned CNTs/CNFs on temperature-sensitive surfaces. Currently there is no process that [...]

Field emission characteristics of carbon nanofibers grown on the electroplated copper micro-tips

Sung W-Y, Kim W-J, Kim Y.H., Lee H.Y., Lee S.M., Yoo H-S, Lee H.Y., Lee S.M., Joo S-K, Kim W-J, Kim Y.H., Seoul National University, KR

Carbon nanofibers (CNFs) were synthesized on micro-copper tips by using direct current plasma enhanced chemical vapor deposition of C2H2 and NH3 gas at 480℃. The copper micro-tips were uniformly formed by high current electroplating and [...]
