Thermally Driven Sound Source: Application of CNT nanofoams

On chip grown CNT nanofoam has a large surface to volume ratio and excellent thermal electrical properties, which is suitable to be used as a thermoacoustic heater. The highly porous foam exchanges heat with surrounding air efficiently. Every processing step is specifically designed to be CMOS compatible using cleanroom microfabrication. This...

Tailoring the Mechanical Properties of High-Aspect-Ratio Carbon Nanotube Arrays using Amorphous Silicon Carbide Coatings

The porous nature of carbon nanotube (CNT) arrays allows for the unique opportunity to tailor their mechanical response by the infiltration and deposition of nanoscale conformal coatings. Here, we fabricate novel photo-lithographically defined CNT pillars that are conformally coated with amorphous silicon carbide (a-SiC) to strengthen the...
