Architecture and analysis of a self-assembled 3D array of carbon nanotubes and molecular memories

Carbon nanotubes and molecular memories have emerged as potential building blocks for functional nano-devices. We analyze the feasibility of integrating single-walled carbon nanotubes and molecular memories into a three-dimensional crossbar array using DNA-directed self-assembly. We describe a process flow for fabricating such arrays and derive design constraints for achieving electromechanical switching with low leakage currents. Finally, we develop a simulation model to incorporate the various device elements.
