the laser growth is patented technique.
price is comparable to gold as I remember.
Right now, Dai's company is making effort to get high quality carbon nanotube. | y***e

发帖数: 578 | 3 I think it may come from arc discharge method because that method wasn't
patented or not completely patented in US. the nanotube produced by arc
discharge has a lot of defect on and can not be used in nano-electronic
research.
go through those references that used nanotube, I found that if they mention
high quality carbon nanotube, they will mention it come from smalley group.
