All the dope on nanotube films

Transparent, conducting, nanotube thin films have shown promise in a number of applications, the range of which has just been increased significantly. Scientists at the National Renewable Energy Laboratory have done much in recent years to advance the understanding and application of these films. In this issue of ACS Nano, Blackburn and colleagues report their study of the doping power of n-type charge transfer donor dopants, finding that hydrazine effects n-type doping approximately comparable in strength to the p-type doping induced by nitric acid. This expands the potential range of applications for such films to electron injection and collection.
