Abstract
The structural organization and the transformation mechanism of the layered carbon phase produced from the tetragonal and rhombohedral variants of the 2D polymers of C-60 were investigated. High Resolution Transmission Electron Microscopy imaging combined with Electron Diffraction analysis were performed for samples synthesized at 2.6, 5.0 and 8.5 GPa and 1100 K. The structure of this layered carbon phase is composed of corrugated layers in a pseudo-epitaxial relationship with the {1 1 1}(cubic) planes of the parent polymer phase. A pseudo-martensitic transformation mechanism is proposed with a partial C-C bond reconstruction, as indicated by measurements of the...
