Atomically Precise Growth and Characterization of Graphene
Abstract
Approach: Proposed project is focused on growing and characterizing graphene nanoribbon (GNR) based heterostructures from the bottom up to create functional, atomically-crafted molecular electronic devices. The team will use rational chemical synthesis and bottom-up defect engineering to control the width, edge chirality, end functionalization, and spatially-varying dopant profile of GNR heterostructrues. They will incorporate these heterostructures into basic circuit configurations and test their performance in applications of relevance to Navy technological goals.The major roadblocks that the team is planning to addres are (i) how to grow GNRs directly on insulators, (ii) how to grow GNRs in a ?block-copolymer? fashion that allows heterogeneous segments ("blocks") along a single GNR to be grown with atomic precision, and (iii) how to grow GNRs with atomically precise edges in the difficult intermediate width regime of 2 nm < width < 12 nm.Objective: The objective of the Graphene Molecular Electronics BRC effort is to explore and exploit the possibility of building electronic devices and circuits from the bottom up, using graphene as a platform, with atomic precision and Angstrom resolution. The program will pursue fundamental research toward building carbon based nanoelectronics from the molecular level up, using molecular synthesis, surface catalytic chemistry and other novel techniques.ONR Mission/Relevance:Graphene as an active electronic material has the potential to allow fabrication of 1 atomic layer thick electronic devices, greatly shrinking electronics and reducing the power consumption of electronic devices. This basic research effort is to improve the scientific understanding of graphene, further develop and validate the theory, and open pathways for the exploitation of this novel material for nanoelectronics.
