A Natural Helical Crystal Lattice Model for Carbon Nanotubes

We propose a novel helical crystal lattice model for chiral and achiral carbon nanotubes (CNTs) where the unit cell and the helical crystal vector are defined in a unique and systematic manner for arbitrary CNTs. The small unit cell of this helical crystal ...

Comparison of Two Different Carbon Nanotube-based Surfaces with Respect to Potassium Ferricyanide Electrochemistry

Giovanni De Micheli, Sandro Carrara, Irene Taurino

This paper describes the electrochemical investigation of two multi-walled carbon nanotube-based electrodes using potassium ferricyanide as a benchmark redox system. Carbon nanotubes were fabricated by chemical vapor deposition on silicon wafer with campho ...

In-situ grown horizontal carbon nanotube membrane

Mihai Adrian Ionescu, Dimitrios Tsamados, Hoël Maxime Guérin

We present the successful fabrication of horizontally grown and dense carbon nanotube (CNT) membranes in situ. A TiN/Al2O3/TiN stack is first patterned to be employed as a support for the CNT growth. Iron is then evaporated with a 45 degrees tilt angle on ...

Comparing the enhanced sensing interfaces of differently oriented carbon nanotubes onto silicon for bio-chip applications

Giovanni De Micheli, Sandro Carrara, Irene Taurino

Carbon nanotubes improve the sensitivity of electrochemical biochips. An optimized integration of the nano/bio/CMOS interface is required to realize accurate and low-cost sensors for applications in personalized medicine. The nanotubes orientation on the c ...

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 ...

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 ...

Nano-Electro-Mechanical Switches Based on Carbon Nanotubes Arrays

Donatello Acquaviva

In the last forty years the semiconductor industry focused on the downscaling process of the CMOS (Complementary Metal-Oxide-Semiconductor) technology, trying to follow as much as possible the empirical Moore's Law. In the last five years this trend has be ...
