CNT Switches and Memories

Carbon-based Devices and Applications


Energy-efficient electronic circuit and system design requires smaller and more efficient switching and memory devices. Due to the technological and scientific limits involved in the miniaturization of CMOS technology, such as leakage and finite subthreshold slope which has resulted in increased power densities in modern chips, the research community has devoted its efforts to the hunt for new materials and structures in order to build the future devices of electronics. Carbon structures like carbon nanotubes (CNTs) and graphene are some of the appealing alternatives to become the basis for the new era of micro and nanoelectronics. The interest in these materials comes from the high intrinsic mobility, mechanical flexibility and electrical tunability that characterize them. Such properties allow the device designer to explore the myriads of possible architectures, such as back-gated, top-gated, wrap-all-around gate, suspended CNTs structures, and CNT-based nano-electromechanical devices. The challenges this project tries to address are the poor reproducibility, reliability and compatibility with mainstream semiconductor devices.
