Low energy electron diffraction (LEED) – Flextura Gate 5

Instrument model:

Technology Description:

The Flextrua cluster growth tool at the Micro and Nanotechnology Laboratory at the University of Oslo (UiO MiNaLab) is connected to an analysis chamber for advanced sample characterization. A plethora of concomitant surface science techniques are available that utilise a variety of photon sources, a state-of-the-art hemispherical electron analyser and low energy electron diffraction optics. The LEED system can resolve the crystalline structure from the top few nanometers of the sample surface.

Technical Information:

System manipulator: Motorised sample manipulator accommodating up to 20 samples with max dimensions of 10x10x1 mm samples. Smaller surface area samples can be measured down to 3×3 mm. LEED analysis on all samples pockets possible.

Low vacuum: 5×10^-7 – 5×10^-10 mBar base pressure.
