Abstract
The structural stability of the tetragonal and rhombohedral two-dimensional (2D) polymeric phases of C60 was studied under pressures up to 27 GPa at room temperature by means of in situ Raman scattering spectroscopy. The results show that the tetragonal 2D phase undergoes an irreversible transformation in the region of 20 GPa while no pressure-induced transitions were observed for the rhombohedral 2D phase. The obtained data are discussed within the framework of recent numerical calculations, which predict the pressure-induced transformation of the 2D polymeric phases of C60 into three-dimensional (3D) polymers in the pressure range 14–20 GPa.
