SWNT array resonant gate MOS transistor

We show that thin horizontal arrays of single wall carbon nanotubes (SWNTs) suspended above the channel of silicon MOSFETs can be used as vibrating gate electrodes. This new class of nano-electromechanical system (NEMS) combines the unique mechanical and e ...

Carbon Nanotube Crossed Junction by Two Step Dielectrophoresis

Mihai Adrian Ionescu, Anupama Arun

The crossed junction formed between a multi walled carbon nanotube (MWCNT) and a bundle of single walled carbon nanotube (SWCNT) is investigated. The junction is fabricated by orthogonally assembling the MWCNT and SWCNT by a two-step dielectrophoresis proc ...

Floating-potential self-assembly of singe-walled carbon nanotube field effect transistors by ac-dielectrophoresis

Mihai Adrian Ionescu, Anupama Arun, Ji Cao

An improved method for self-assembly fabrication of single-walled carbon nanotube (SWCNT) field effect transistors (FETs) is presented, combining the unique design of biased/floating potential electrode geometry and the technique of aligning CNTs by pre-de ...

Carbon Nanotube Electromechanical Devices for Radio Frequency Applications

Anupama Arun

Carbon nanotubes (CNT) have been investigated extensively in the recent years for application in nano-electromechanical systems (NEMS). CNTs have extraordinary electrical and mechanical properties. They are stiff, with low density, high electrical conducti ...

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

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

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 ...

Trapping Individual Carbon Nanotubes

Mihai Adrian Ionescu, Anupama Arun

A technique to deterministically manipulate individual Carbon Nanotubes (CNT) has been the brick-wall for the boom of CNT based devices. Here we demonstrate dielectrophoresis as an efficient technique to trap individual Single Walled Carbon Nanotubes (SWCN ...
