CIC nanoGUNE offers External Services with the aim of supporting the characterization and fabrication of materials and micro and nanoscale devices for both academic and industrial users. The External Services Department is designed to be an open facility for researchers and technologists from different business and research fields.
The services offered by the External Services Department can be carried out by qualified nanoGUNE personnel or requested under a self-service mode.
Please contact the External Services Department staff.

Description: 

X-ray diffraction/reflection system and atomic-force microscopes, as well as last generation electron microscopes, specifically an environmental scanning electron microscope (ESEM, FEI Quanta 250) and a transmission electron microscope (TEM, FEI Titan). These systems are operated by highly qualified scientists which are capable of a complete processing, simulation, and visualization of the electron-microscopy data.

Services: 

X-ray reflectivity/diffractometry
Thin film characterization:
X-ray reflectivity (XRR): thickness and quality characterization of single thin films or complex multiple thin films samples.
X-ray diffractometry (XRD)
Basic crystallographic characterization (crystal phase identification and basic crystal plane characterization)
Detailed crystallographic characterization (crystal cell parameter calculation, crystal orientation determination, texture analysis…)
Powder characterization:
X-ray diffractometry (XRD): crystal phase characterization
