Experimental setup for high energy photoemission using synchrotron radiation
The instrument VOLPE (volume photoemission from solids) is an experimental setup dedicated to high energy photoemission (PE) experiments. The instrument is equipped with an electrostatic hemispherical spectrometer especially designed to analyze high energy ...
American Institute of Physics2005On recent developments for high-speed atomic force microscopy
The atomic force microscope (AFM) is limited in imaging speed by the bandwidth and dynamic behavior of the actuators and mechanical parts. For high-speed imaging all AFM components have to be optimized in performance. Here, we present improvements of the f ...
2005Nanostenciling: a Versatile Approach for Surfaces Patterning
Jürgen Brugger, Marc Antonius Friedrich van den Boogaart
A versatile method for parallel nanoscale structures fabrication and patterning, using a combination of stencil-mask and pulsed-laser deposition (PLD) techniques is presented. A miniature shadow-mask with nano-apertures in a very thin microfabricated membr ...
2004STM study of terephthalic acid self-assembly on Au(III): Hydrogen-bonded sheets on an inhomogeneous substrate
Klaus Kern, Harald Brune, Sylvain Clair
The adsorption and ordering of the molecule terephthalic acid (TPA), 1,4-benzene-dicarboxylic acid C6H4-(COOH)(2), on the reconstructed Au(111) surface has been studied in situ in ultrahigh vacuum by scanning tunneling microscopy (STM) at room temperature. ...
American Chemical Society2004Propriétés magnétiques de nanostructures de cobalt adsorbées
This thesis reports results on magnetic properties of supported cobalt nanostructures. The nanostructures were grown on single crystal metal surface by Molecular Beam Epitaxy in an Ultra High Vacuum chamber. Our experimental setup is based on two in situ m ...
EPFL2004Optimization of the fabrication of sealed capacitive transducers using surface micromachining
Processing issues for the fabrication of capacitive micromachined ultrasonic transducer (cMUT) arrays have been studied using surface micromachining. This work focuses on the critical steps of process fabrication such as membrane formation, sacrificial lay ...
2004High-coverage structures of carbon monoxide adsorbed on Pt(111) studied by high-pressure scanning tunneling microscopy
High-pressure scanning tunneling microscopy was used to study the room-temperature adsorption of CO on a Pt(111) single-crystal surface in equilibrium with the gas phase. The coverage was found to vary continuously, and over the entire range from 10(-6)-76 ...
2004Nucleation and growth of ultrathin pentacene films on silicon dioxide: effect of deposition rate and substrate temperature
Frank Nüesch, Libero Zuppiroli
We report on a study of pentacene thin-films grown by high vacuum deposition on silicon dioxide, using atomic force microscopy (AFM) and transmission electron microscopy (TEM). The nucleation density of pentacene islands on SiO2is found to rise ...
Elsevier2004Large area deposition in high vacuum with high thickness uniformity
Patrik Willi Hoffmann, Simone Amorosi, Giacomo Benvenuti
The invention relates to an effusing source for film deposition made of a reservoir comprising one hole characterized by the fact that the hole diameter is less than one order of magnitude than the mean free path of the molecules determined by the pressure ...
2004High resolution photodetachment spectroscopy of negative ions via slow photoelectron imaging
A technique for high resoln. anion photodetachment spectroscopy is presented that combines velocity map imaging and anion threshold photodetachment. This method, slow electron velocity-map imaging, provides spectral line widths of better than 1 meV. Spectr ...
