Striking Influence of the Catalyst Support and Its Acid–Base Properties: New Insight into the Growth Mechanism of Carbon Nanotubes

Arnaud Magrez, Gabor Laurenczy, Endre Horvath, Jin Won Seo, Rita Smajda, Donatello Acquaviva, Juan Carlos Andresen

In the accepted mechanisms of carbon nanotube (CNT) growth by catalytic chemical vapor deposition (CCVD), the catalyst support is falsely considered as a passive material whose only role is to prevent catalytic particles from coarsening. The chemical chang ...

Tunable MEMS capacitors using vertical carbon nanotube arrays grown on metal lines

Mihai Adrian Ionescu, Montserrat Fernandez-Bolanos Badia, Donatello Acquaviva, Anupama Arun

In this work, tunable MEMS capacitors are realized using a vertically grown carbon nanotube array. The vertical CNT array forms an effective CNT membrane, which can be electrostatically actuated like the conventional metal plates used in MEMS capacitors. T ...

Capacitive nanoelectromechanical switch based on suspended carbon nanotube array

Mihai Adrian Ionescu, László Forró, Arnaud Magrez, Didier Bouvet, Rita Smajda, Donatello Acquaviva, Anupama Arun

We present the fabrication and high frequency characterization of a capacitive nanoelectromechanical system (NEMS) switch using a dense array of horizontally aligned single-wall carbon nanotubes (CNTs). The nanotubes are directly grown onto metal layers wi ...
