Method for constructing a carbon molecule and structures of carbon molecules

摘要

Carbon atoms are arranged stably in the form of a torus or in the form of a helical coil to give novel topological properties to the carbon atoms to thereby provide various functions of carbon molecules. A plurality of sixfold rings each including six carbon atoms are arranged in the form of a torus, and then these sixfold rings are partially replaced by fivefold and sevenfold rings to obtain a stable structure. That is, a part of the outer wall surface of a torus constituted by a plurality of sixfold rings and a part of the inner wall surface of the torus are replaced by fivefold rings and sevenfold rings respectively to obtain a stable structure. Further, a molecule in which carbon atoms are arranged to form a toroidal or helically-coiled stable structure or a cluster in which a plurality of such molecules are arranged spatially is constructed by using an STM. Further, a micro part or device using the hole of the torus/helical coil and the inside of the ring thereof is formed by combining a plurality of such molecules/clusters.
