摘要：

We study the two-dimensionally polymerized rhombohedral phase of C-60 by using the local-density approximation in the density-functional theory. The electronic structure of this hybrid solid carbon of sp(2) and sp(3) C atoms is found to be essentially three dimensional with a narrow fundamental gap due to a strong interlayer interaction, which also stabilizes the system considerably. Possible modifications of this elemental semiconductor are also discussed.
