Flexible high conductivity carbon nanotube interconnects made by rolling and printing
S. Tawfick, K.P. O’Brien, A.J. Hart.Small 5(21):2467-2473, 2009. [http://dx.doi.org/10.1002/smll.200900741] [PDF] Applications of carbon nanotubes (CNTs) in flexible and complementary metal-oxide-semiconductor (CMOS)-based electronic and energy devices are impeded due to typically low CNT areal densities, growth temperatures that are incompatible with device substrates, and challenges in large-area alignment and interconnection. A scalable method for continuous…
