A hybrid on-chip optonanomechanical transducer for ultra-sensitive force measurements

We realize an integrated hybrid optonanomechanical transducer for the detection of weak forces. We propose and demonstrate with our system that dissipative feedback dramatically decreases the averaging time necessary to detect an incoherent force. (C) 2011 ...

A vibration suppression approach to high-speed atomic force microscopy

Georg Fantner

The possibility of many new applications and novel scientific observations can be provided by efficient and reliable high-speed atomic force microscopy techniques. However, the reliability of the AFM images decreases significantly as the imaging speed is i ...

Automatic lateral resonance identification from cantilever deflection information in high speed atomic force microscopy

Georg Fantner

As progress in nanotechnology and molecular biology advances, demand for high speed and high quality imaging techniques have increased to the point where image acquisition rates in atomic force microcopy (AFM) become impediments to further discovery. High ...

Invited Review Article: Technology for Attosecond Science

Christopher Alexander Arrell

We describe a complete technological system at Imperial College London for Attosecond Science studies. The system comprises a few-cycle, carrier envelope phase stabilized laser source which delivers sub 4 fs pulses to a vibration-isolated attosecond vacuum ...

An experimental setup combining a highly sensitive detector for reaction products with a mass-selected cluster source and a low-temperature STM for advanced nanocatalysis measurements

Harald Brune, Wolfgang Harbich, Michael Hugentobler, Simon Bonanni

We report on a home-built detector for catalytic reaction measurements offering good gas isolation from the surrounding ultrahigh vacuum components, high sensitivity for reaction products and a fast response time of 10 ms enabling dynamic studies correlate ...

Structure Sensitivity of Alkynol Hydrogenation on Shape- and Size-Controlled Palladium Nanocrystals: Which Sites Are Most Active and Selective?

Lioubov Kiwi, Rocio Micaela Crespo Quesada, Artur Yarulin

The activity and selectivity of structure-sensitive reactions are strongly correlated with the shape and size of the nanocrystals present in a catalyst. This correlation can be exploited for rational catalyst design, especially if each type of surface atom ...

Sub-Micron Nano-Composite CoC Hall Sensors by Focused Electron-Beam Induced Deposition for Microbead Detection

Laurent Bernau

In order to track single superparamagnetic microbeads serving as markers in biomolecular assays, high-sensitivity, sub-micron magnetic sensors which can be integrated onto Lab-on-a-chip platforms are needed. This thesis studies the realization and characte ...

Diamond overgrown InAlN/GaN HEMT

Nicolas Grandjean, Jean-François Carlin

In this work the technology and characterization of nanocrystalline diamond (NCD) films directly grown on InAlN/GaN HEMTs is presented. Optimization of GaN based HEMT process steps including metallization stacks is discussed. A fully processed InAlN/GaN HE ...

IMPEDANCE EFFECTS IN THE CLIC DAMPING RINGS

Nicolas Frank Mounet, Eirini Koukovini Platia, Benoît Salvant, Giovanni Rumolo

Due to the unprecedented brilliance of the beams, the performance of the Compact Linear Collider (CLIC) damping rings (DR) is affected by collective effects. Single bunch instability thresholds based on a broad-band resonator model and the associated coher ...

Electrochemical promotion of CO combustion over non-percolated Pt particles supported on YSZ using a novel bipolar configuration

Christos Comninellis, Wolfgang Harbich, György Foti, Michael Hugentobler, Chun Xia

The electrochemical promotion of CO combustion over nano-dispersed Platinum particles supported on yttria stabilized zirconia (YSZ) is investigated at 300 degrees C under high vacuum conditions. By polarizing the nanoparticles, we were able to enhance the ...
