Abstract Scope |
Aerosol jet printing (AJP) enables the printing of a wide range of electronic materials at 10-100 μm resolution. An investigation into the deposition of carbon nanotubes (CNTs) by AJP as a novel material for use in electronic interconnects has been conducted. CNTs are attractive for interconnects due to their long mean free path and large current carrying capacity.[1] AJP process conditions for single walled CNTs in water-based inks were optimized to generate linewidths of 100 μm. Here, we will present our findings and characterization of CNT microstructure, alignment and chemical structure by SEM, transmission microscopy and Raman spectroscopy. A comparison of the electrical resistance of the printed CNT lines before and after annealing will also be shown.
