Cluster Laboratory
 

The laboratory is equipped with unique for Denmark magnetron sputtering cluster apparatus (MaSCA) capable in formation of atomic clusters (nanoparticles) of various materials in vacuum.

The particles are collimated into a beam and can be deposited on a substrate in a controllable manner (one can tune nanoparticle size and surface coverage).

Scanning Probe Microscopy (SPM) Facilities
 

The Department possesses a range of microscopes including Solver Pro, Ntegra-Aura with P9 controller, Ntegra Life combined with Olympus X71 fluorescence microscope, Nanoscope IIIa with SPMLab Phoenix controller and Nanonics MultiView 4000.

These systems cover ordinary contact, semi-contact and non-contact atomic force microscopy (AFM) as well as a number of other modes to carry out/measure force spectroscopy, lateral forces, electrostatic forces, Kelvin probe, magnetic forces, spreading resistance and more.

Ntegra-Aura provides a possibility to carry out measurements in low vacuum or controlled atmosphere. Ntegra Life is capable to work both in air and in liquid. Topography and mechanical properties (as force-distance curves) can be measured simultaneously with the fluorescence imaging.

Nanonics system allows measurements with multiple custom probes for e.g. electrical and electrochemical characterization also with free optical access to the sample and possibility of nanomanipulations.

More details can be obtained from Dr. Vladimir Popok, vp@mp.aau.dk or Dr. Leonid Gurevich, lg@mp.aau.dk.

A RT STM and a Cryogenic Scanning Tunneling Microscope that operates at 5 K under Ultra High Vacuum conditions for imaging with atomic resolution and spectroscopy with meV resolution. It is possible to apply a magnetic field (up to 2 T) to the sample under investigation.

The setup contains a range of in-situ sample preparation and fabrication techniques (sputtering, annealing, evaporation of metals (thin films / nanostructures) and molecules). The option to perform surface diffraction studies using Low Energy Electron Diffraction (LEED) is also available.
