Electronic Chemicals: Physicists Apply Electrical Field to Enhance Semiconducting Properties of Nanotubes

Physicists at the University of Gothenburg (Gothenburg, Sweden) say they have developed a method to better control the form of nanotubes during production by using electrical fields. The technique could enable carbon nanotubes, a semiconducting material, to replace silicon in electronic applications, the researchers say.   “Carbon nanotubes grow randomly and it is not possible to control either their position or direction. Therefore I have applied an electrical field to guide the tubes as they grow,” says Johannes Svensson, the project...
