Imaging of molecules, lattice and lattice defects in C60–C70fullerites by high-resolution electron microscopy

Abstract

C₆₀–15% C₇₀ fullerite powder specimens have been studied by high-resolution transmission electron microscopy. Electron diffraction shows the coexistence of f.c.c. and h.c.p. crystallites in the thermally pre-treated fullerite powder. In the high-resolution micrographs the spherical confour of the fullerene molecules is identified and compared with image simulations. In addition to nearly-defect-free crystallites, defected areas with stacking faults and twins were observed.
