Investigation of single WS₂ nanotubes leads to new observations and potential applications

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 results 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.
