US 5,401,975 A · Method for constructing a carbon molecule and structures of carbon molecules

Abstract

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.

A method for constructing a toroidal molecule, comprising the steps of:

forming a toroidal molecule such that a plurality of sixfold rings each including six atoms are arranged in a torus form, while changing external physical force to be applied to the atoms;
changing the atoms arrangement of said toroidal molecule such that first ones of said sixfold rings arranged on an outer wall surface of said toroidal molecule are replaced by first fivefold rings each including five atoms, said first sixfold rings being apart from each other;
and
changing the atoms arrangement of said toroidal molecule such that second ones of said sixfold rings arranged on an inner wall surface of said toroidal molecule are replaced by second fivefold rings each including five atoms and sevenfold rings each including seven atoms, said second sixfold rings being apart from each other,
wherein each of said first and second fivefold rings and said sevenfold rings is surrounded by said sixfold rings.
