Millimeter-sized C60 single crystals with regular, shiny and smooth faces were grown from vapor phase. The structure of C60 crystals was confirmed to be face-centered-cubic (fcc, a = 1. 4199(4) nm) by X-ray diffraction at room temperature. The morphologies and growth defects were studied by both the scanning electron microscope and the optical microscope. In addition to the typical stable 111 and 200 faces and twins for fcc crystals, we also observed the dentrites,ridge like defects and growth hillocks on 111 faces and dentrites,growth hillocks and swimming-pool-like defects on 200 faces. The morphologies appeared were compared with the theoretical equilibrium forms. The mechanism of the formation of the growth defects were analysed. The effects of growth conditions on the growth morphology of C60 crystals were discussed. These results will be helpful for the investigation or the growth mechanism of C60 single crystals by vapor transport method.
