XRD background
XRD
X-ray diffraction (XRD) is a technique primarily used for phase identification of a crystalline material and can provide structure information on unit cell dimensions. It is also used for crystallinity determination if the samples contain both crystalline and amorphours phase.
Condition required for diffraction has to fulfill Bragg's Law
Stages available for Rigaku XRD
There are 3 stage available for Rigaku XRD, standard stage (for powder and bulk sample), Auto-Sample-Changer (ASC-10) stage (for up to 10 powder samples run in one-click), and multi-purpose stage for thin film sample as well as in-plane scan.
Standard stage,
max sample dimensions 30*30*35 mm (LWH)
ASC-10 stage,
max sample dimensions 12*12*2 mm (LWH)
Multi-purpose stage,
max sample dimensions, max 8 mm in height
In-Plane Technique
Powder XRD sample usually use out-of-plane technique by scan 2Theta/theta for phase identification.
For thin film sample, the typical scan is fixed glancing angle as omega, and perform 2Theta scan. Sometimes, in-plane scan of 2Theta/Phi/Chai could be used for phase ID and crystal structure if the interested phase is different to substrate normal.
CBO (Cross Beam Optics) and Focus Beam (FB)/Parallel Beam (PB)
Focus beam will provide more flux of x-ray to sample. It penetrate deeper to the sample (~3-4 um for stainless steel, 2mm for organic). While PB has ca. 1/10 flux of the FB, and is less sensitive to sample morphology and is usually used for sample with uneven surface. PB is also use for glancing angle analysis as well because the penetration is less. Rigaku equipped with advanced Cross Beam Optics (CBO) unit in the incident X-ray beam, FB or PB can be switched by simply pushing in the selectable slit.

Source and Choice of Detection
Rigaku XRD equipped with Cu x-ray source. The K-beta peak can be removed from monochromator or K-beta filer. If sample contain large amount of Fe, Mn, strong x-ray fluorescent signals would be observed and monochromator can be used to remove the fluorescence.
K-beta Filer
Monochromator
XRD Sample Preparation
XRD signal would be stronger if the samples are flat and with a crystalline size of 10-50 um. Sample surface is required on the same level of the sample holder, otherwise 2theta shift would be observed.
Software to process the data
Currently, we have Jade 9.0 for the data acquired from Rigaku XRD. The software is licensed and only accessible through computer in nanoFAB computing area. Jade software can perform Database Search/Match for phase identification, and crystallinity determination, as well as crystalline size analysis. Data can be exported to text file too.
