Resist-assisted assembly of single-walled carbon nanotube devices with nanoscale precision

Mihai Adrian Ionescu, Ji Cao, Clemens Benedict Nyffeler

We report a novel resist-assisted dielectrophoresis method for single-walled carbon nanotube (SWCNT) assembly. It provides nanoscale control of the location, density, orientation and shape of individual SWCNTs. Sub-50 nm accuracy and a yield higher than 85 ...

Monolithic integration of Si nanowires with metallic electrodes: NEMS resonator and switch applications

Davide Sacchetto, Yusuf Leblebici, Izzet Yildiz

The challenge of wafer-scale integration of silicon nanowires into microsystems is addressed by developing a fabrication approach that utilizes a combination of Bosch-process-based nanowire fabrication with surface micromachining and chemical-mechanical-po ...

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 ...

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 ...

A Nanoscale Parametric Feedback Oscillator

Luis Guillermo Villanueva Torrijo

We describe and demonstrate a new oscillator topology, the parametric feedback oscillator (PFO). The PFO paradigm is applicable to a wide variety of nanoscale devices and opens the possibility of new classes of oscillators employing innovative frequencydet ...
