Central Facilities

NCMN Central Facility for Electron Microscopy

The function of the Central Facility for Electron Microscopy is to provide hands-on access to electron microscopes, sample preparation equipment plus data collection and data reduction instrumentation, along with advice, training and research collaboration. The scope of the Facility is materials characterization of the topography, morphology, elemental composition, crystalline microstructure, crystal defects, and atomic arrangements of materials, largely on a scale from 10 micrometers down to the near-atomic level.

Specimen Preparation

(1) FEI Tecnai Osiris (S)TEM

Fully digital 200 kV TEM and STEM system including the HAADF detector X-FEG
high brightness Schottky FEG. 
Super-X windowless EDX detector and EELS system. Biprism for holography
and tomographic holder.

(2) FEI Nova NanoSEM450

Field emission SEM with ultra-stable, high current Schottky gun. Advanced optics and detection, including immersion mode, beam deceleration, in-lens TLD-SE and -BSE, DBS and STEM for best selection of the information and image optimization.

(3) JEOL JEM 2010 TEM

200kV, analytical/high-resolution mode, LaB6 filament, single-tilting and double-tilting sample holders. (Oxford EDS system, Gatan dual-view CCD camera, TSL texture analysis system, Digi-TEM beam control system).

(4) Specimen Preparation Equipment

Various  equipment for TEM and SEM specimen preparation, including slow speed diamond/wire saw; ultrasonic/rotation disc cutter; dimpling grinder; metallurgical polishing wheel; ion-polishing PIPS/PIPS II; plasma nanoclean; Au/C sputter coater.

Users of the facility:

The Facility is accessible to all qualified researchers at UNL, at other universities and in industrial and other laboratories on payment of the appropriate charges.

Under normal circumstance, these researchers will be expected to have the requisite background knowledge for electron characterization of materials before some training will be given for a particular instrument.

In some cases, research collaboration is possible for common research interests and/or if researchers need the capabilities of the equipment and experienced examination of samples but are unable to use the facilities for themselves. Limited full service handling and examination of materials is available for these researchers according to availability of the facility specialist.
