Upto how much %age of phase can be visible as peak in XRD?

When we do XRD analysis, high intensity peaks are obtained. But there are some very small peaks too which seem to be negligible. Some phases are confirmed from SAED pattern on the basis of...

How do I determine the d spacing and ultimately the hkl values of monocrystalline materials from the SAED pattern?

Below I've attached the image I got from SAED of my material and I'm trying to determine the d spacing and ultimately its hkl values. I used Fiji image J TEM suite for my other samples which were...

Is it possible to get higher order of diffraction (n>1) in HRTEM?

The SAED pattern, we obtained from HRTEM shows the interplanar spacing (d) that corresponds to a higher 2theta value than the Powder crystal X-ray diffraction pattern for the same organic...

How to convert a SAED pattern into a 2D plot like XRD profiles (using GMS3)?

I try to use the line profile, but it just intersects with a few spots in the whole SAED pattern. Is there any way to sum all the spot intensity as a function of distance in reciprocal space?

Is it possible to get amorphous nature from the SAED pattern ( diffused rings) and lattice fringes from the TEM image for the same sample?

For my sample, diffused rings are observed in SAED pattern which is due to the amorphous nature of the sample. In XRD also, amorphous nature is reflected by the presence of broad peaks. But, in...

NBED versus SAED?

I hardly see any published results for electron diffraction done using the nanobeam ED settings. Is there a reason for prefering SAED over NBED?

I have a SAED pattern of the hybrid nanostructure (metal and semiconductor) but I am not sure what information should I get from this image?

This SAED pattern is generated for a metal semiconductor hybrid nanostructure. I can see it's not single crystalline but I am not sure how to index the planes? Could you please help?
