* 2000 – First demonstration proving that bending carbon nanotubes changes their resistance
* 2001 April — First report on a technique for separating semiconducting and metallic nanotubes.
* 2002 January — Multi-walled nanotubes demonstrated to be fastest known oscillators (> 50 GHz).
* 2003 September — NEC announced stable fabrication technology of carbon nanotube transistors.
* 2004 March — Nature published a photo of an individual 4 cm long single-wall nanotube (SWNT).
** May — A prototype high-definition 10-centimetre flat screen made using nanotubes was exhibited.
** August — University of California finds Y-shaped nanotubes to be ready-made transistors.
** August — General Electric announced the development of an ideal carbon nanotube diode that operates at the "theoretical limit" (the best possible performance). A photovoltaic effect was also observed in the nanotube diode device that could lead to breakthroughs in solar cells, making them more efficient and thus more economically viable.
** August — Nanotube sheet synthesised with dimensions 5 × 100 cm.
** March — IBM announces that they have built an electronic circuit around a CNT.
** March — Nanotubes used as a scaffold for damaged nerve regeneration.
** May — Method of placing nanotube accurately is developed by IBM.
** June — Gadget invented by Rice University that can sort nanotubes by size and electrical properties.
** July — Nanotubes were alloyed into the carbon fiber bike that was ridden by Floyd Landis to win the 2006 Tour de France.
** April — Nanotubes incorporated in virus battery.
** A single-walled carbon nanotube was grown by chemical vapor deposition across a 10-micron gap in a silicon chip, then used in cold atom experiments, creating a blackhole like effect on single atoms.
