XRD SmartLab

The Rigaku SmartLab is an advanced XRD for measuring on thin films. All thin films can be measured without fixating the sample, as the system has a so called In-Plane arm.

The XRD SmartLab located in cleanroom F-2


The user manual(s), user APV(s), technical information, and contact information can be found in LabManager:

XRD SmartLab in LabManager - requires login


Various measurement types including X-Ray reflectivity, Rocking curve, Theta-2theta, and Pole figures are described here:

Process information


The measurement settings and results of the pre-acceptance test are described in this document, also found on the Lab Manager:

The same measurement were completed as part of the acceptance, but no report was generated. In addition the inspection certificate is available here:


Software for analysis

Please see the Data Analysis section at the main XRD page.

Characterization of thin films using X-ray reflectivity (XRR)

Implementing the XRR method the user can calculate thickness, density, and roughness of the deposited material. The XRR is also widely employed for multilayer stack analysis.

Here are some results available:


Grazing Incidence X-ray Diffraction XRD (GiXRD)


θ/2θ X-ray Diffraction
