Insights into carbon nanotube nucleation: Cap formation governed by catalyst interfacial step flow
Rahul Rao, Renu Sharma, Frank Abild-Pedersen +2
In order to accommodate an increasing demand for carbon nanotubes (CNTs) with desirable characteristics one has to understand the origin of helicity of their structures. Here, thro…
