Hi Pramod, Can you forward me the results so that I can have a look.

Flemming B. Grumsen

This is an effect that can be observed by insufficiant grain statistics. What is your crystallite size?

Savan V Katba

I have taken PHI scans of many substrates but never came across this type of issue. Generally, sharp peaks are observed.

Please check, whether this doublet is from the K-Alpha 1 and 2 both ???

Use of monochromator solves this type of doublets in routine XRD measurements.

Thanks
