DESCRIPTION:Recent progress in bulk CNT growth has boosted their yield and
  availability. However\, potential large scale application also requires c
 ontrolled assembly and more deterministic control of CNT properties. It is
  commonly assumed that the catalyst metal forms a liquid intermediate and 
 that bulk catalyst effects dominate CNT growth dynamics. Calculations of s
 ize-corrected melting points and carbon saturation often indicate minimum 
 CNT synthesis temperatures >500C. This talk will focus on recent work at t
 he Department of Engineering in Cambridge. In particular it will be shown 
 how single-wall CNTs and carbon nanofibres can be grown at temperatures be
 low 400C with a high level of control. Combined with ab-initio calculation
 s\, different perspectives of catalytic CNT growth will be reviewed.
