HETEROJUNCTION GRAPHENE NANORIBBON, RESONANCE TUNNEL DIODE AND PRODUCTION METHOD OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a stable production method of a graphene nanoribbon heterostructure with controlled lengths of respective regions, concerning a heterojunction graphene nanoribbon, a resonance tunnel diode, and a production method of the same.SOLUTION: A heterojunction graphene nanoribbon comprising a first graphene nanoribbon element 3 and a third graphene nanoribbon element 5, which are arranged on a substrate 1, of which the edge structure along the longer direction is an arm chair type, and of which the widths in the shorter direction are different from each other, is formed by covalent-bonding both ends of the first graphene nanoribbon element 3 with second graphene nanoribbon elements 4 in the longer direction, and by covalent-bonding an end of the second graphene nanoribbon element 4 with the third graphene nanoribbon element 5 in the longer direction.SELECTED DRAWING: Figure 1
