IMAGING OF MOLECULES, LATTICE AND LATTICE-DEFECTS IN C-60-C-70 FULLERITES BY HIGH-RESOLUTION ELECTRON-MICROSCOPY

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 contour of the fullerene molecules is identified and compared with image simulations. n addition to nearly-defect-free crystallites, defected areas with stacking faults and twins were observed.
