Office of Naval Research Research Opportunity : Basic Research Challenge : Carbon Molecular Electronics
The proposed topic will 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.
Background:
The 2010 Nobel Prize for physics was awarded to Prof. Andre Geim and Prof. Kostya Novoselov for isolating and elucidating the peculiar physical properties of two-dimensional material graphene. The application potential of graphene for electronics was recognized early on, due to its record - breaking mobility, thermal conductivity and mechanical strength. However, despite the enormous progress that has been made in graphene research during the last few years, some of the more unusual and exotic properties unique to graphene, such as the predicted edge magnetism and the tunable intrinsic bandgap in graphene nanoribbons, remain poorly understood and awaiting to be exploited for device functionalities. Part of the challenges stem from our inability to control, assemble and synthesize atomically precise graphene nanostructures with desired shape and dimensions. Recent progress in chemical techniques using surface catalysis on metal substrate is highly encouraging. Using copper catalyzed chemical vapor deposition (CVD) technique, single atomic layer graphene sheets as large as 30 inches have been synthesized. On the other extreme, using surface - assisted polymerization of carbon -containing molecular precursors and their subsequent cyclodehydrogenation process, graphenenanoribbons that are 12 nm wide with atomically precise edges, have been reported. These chemical and molecular synthesis techniques show great promise and could enable construction of carbon based electronics all the way from molecular scale building blocks to macroscale gadgets.
