(Invited) Investigation of Single WS2 Nanotubes Leads to New Observations and Potential Applications

Abstract

High temperature synthesis of different nanotubes (INT) and fullerene-like (IF) nanoparticles from inorganic layered compounds, like WS2 and numerous others has ensued a rich chemistry. Scaling up the production of IF/INT-WS2 resulted in numerous commercial applications, particularly as superior solid lubricants. To exploit the full potential of these nanoparticles we are developing extensive series of experimentations with individual nanotubes/nanoparticles. One of the main advantages of this approach is the possibility to confront the experimental data with detailed model calculations. Several approaches for this kind of strategy are demonstrated in the presentation, in particular in relation to their mechanical, electronic and optical properties.
