Crystalline films of fullerene C60have been grown on amorphous substrates by a physical vapor deposition technique. X‐ray diffraction has shown that these C60films are highly oriented in either (111)/(glass substrate) or (220)/(fused silica substrate) orientations. The explanation for such growth behavior is that the orientation of C60crystals can be adjusted during growth by the rotation of individual C60molecules at elevated temperatures. ©1995 American Institute of Physics.
