Technical characteristics:

SmartLab makes thin films analysis more flexibile. SmartLab approach is to aid users in choosing the specific measurement conditions, experimental geometries and application methods best suited to their particular sample.

Description

The system is multimodular (quick alignement computer aided, small measurement time), modern techniques for producing X-ray sources, real time ultraspeed detectors and difraction data processing  (especialized software, databases, etc).

Multiple measurement techniqus:

• X-ray Powder diffraction (XRPD);
• High resolution X-ray diffraction (HRXRD) (including multiple refflection HR-MRXRD Ge(220) 2 and 4 bounce monochromator, Ge(220) 2 bounce analyzer, focussing/ flat diffracted beam monchromator);
• X-ray reflectometry (XRR, including HRMR XRR);
• Grazing incidence diffraction (GIXRD);
• In-plane grazing incidence diffraction (IPGID);
• Small angle X-ray scattering (SAXS);
• Single crystal diffraction (SCD);

Some of the characterized structure parameters are:

• multilayer structure- thickness (1~ 103 nm), density (H2O ~ Heavy metals), roughness ( 0.2 ~ several nm);
• phase identification- interface, transition layer;
• crystal structure- crystal quality, lattice parameter (several nm);
• crystal orientation - single: orientation relation of the substrate and film;
• poly: preffered orientation;
• particle/pore size analysis- 1~ 102 nm;

**********************

Applications:

crystal structure (HR RSM, HR RC);
film thickness, density, roughness;
characterization of the ultra thin film (in plane XRD);
particle/ pore size analysis (reflection SAXS, transmission SAXS);
phase identification, crystal structure (powder/thin film/poly/ mono/ crystall, trace, small area/quantity);
