Plasma prefers semiconducting nanotubes
Researchers at Stanford University, US, have found that a plasma-enhanced chemical vapour deposition (PECVD) technique can produce high-quality single-walled carbon nanotubes at low growth temperatures - around 600°C. What’s more, in an unexpected bonus, almost 90% of the resulting nanotubes were semiconducting.
