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 ...

Integration for All Configurations

Mihai Adrian Ionescu

Since their discovery in 1991 [1], carbon nano-tubes (CNTs), have been considered among the most promising materials for logic nanodevices, interconnects and nanoelectromechanical systems (NEMS). They have remarkably unique mechanical (Youngs modulus up to ...

Improving the Electrical Conductivity of Carbon Nanotube Networks: A First-Principles Study

Nicola Marzari

We address the issue of the low electrical conductivity observed in carbon nanotube networks using first-principles calculations of the structure, stability, and ballistic transport of different nanotube junctions. We first study covalent linkers, using th ...

High Throughput Nanofabrication of Silicon Nanowire and Carbon Nanotube Tips on AFM Probes by Stencil-Deposited Catalysts

Jürgen Brugger, Andreea Veronica Savu

A new and versatile technique for the wafer scale nanofabrication of silicon nanowire (SiNW) and multiwalled carbon nanotube (MWNT) tips on atomic force microscope (AFM) probes is presented. Catalyst material for the SiNW and MWNT growth was deposited on p ...

Switchable Conductance in Functionalized Carbon Nanotubes via Reversible Sidewall Bond Cleavage

Nicola Marzari

We propose several covalent functionalizations for carbon nanotubes that display switchable on/off conductance in metallic tubes. The switching action is achieved by reversible control of bond-cleavage chemistry in [1 + 2] cycloadditions via the sp(3) reve ...
