| The excellent electronic, thermal and mechanical properties of single-walled carbon nanotubes (SWNT) and graphene sheets, together with the ability to integrate them onto a wide range of substrate types, create opportunities for their use in various areas of electronics, ranging from heterogeneously integrated systems for applications in communications to large area distributed circuits for flexible displays. In these cases, aligned arrays of pristine SWNTs and rationally synthesized graphene-like materials have the potential to provide thin film semiconductors for scalable circuit integration. This talk describes our research in this area, and highlights (1) methods for self-aligned growth of large scale, perfectly aligned arrays of perfectly linear SWNTs, (2) approaches to make multilayer, superstructures of these arrays, and (3) some recent work on chemically synthesized conjugated carbon monolayers in flat sheets and 3D structural layouts. Transistor and circuit implementations of these materials, including a variety of analog nanotube RF systems such as transistor radios, that illustrate some of the electrical, mechanical and optical properties that can be achieved will be presented. |
