Sample Preparation

Comprehensive equipment is available to prepare plan-view and cross-sectional samples from a large variety of inorganic and organic materials. The most important tools are mentioned in the following list. If you are interested to utilize that equipment for your own research, please directly contact Prof. Dr. Benjamin Butz.

Optical (light) microscopes

  • High-resolution OM Leica DM6 (plan-apochrom. lenses, res <1 µm, BF/DF/DIC/pol, autom. 3D/topo/tiling)
  • Digital HR-OM Leica DMV for large samples (plan-apochrom. lenses, res <1 µm, BF/DF, autom. 3D/topo/tiling)
  • Laser confocal microscope Olympus 3D LEXT OLS 4000 (Christ group)
  • Other high-resolution OM, several stereo microscopes (partly with camera)

Mechanical preparation

  • Several precision diamond disc saws
  • Diamond-wire saw (Diamond WiretecDWS100) & Lapping wire saw (KDUnipress WS-22)
  • Several grinding/polishing tools
  • 2 dimplers (Gatan)

Cross-sectional preparation of complex coatings & devices

  • DualBeam FIB/SEM FEI Helios NanoLab 600
  • Ultramicrotome Leica UC7 (for TEM, SEM)
  • Trimming tool Leica TRIM2
  • Jeol cross-section polisher IB-19500CP (for SEM, OM)
  • Comprehensive embedding equipment including safety vessel for pressure infiltration
  • Current students’ Design & Development Project (PEP): cryo battery cross-sectioner
