When crystals like diamond are grown by CVD method then grown crystals have some specific orientation.
How we can identify the crystal orientation like (100) or (110). Is there any specific analytic technique or with the help of SEM or optical microscope it is possible?
Dear Asraful Haque,
I am using powder XRD as well as single XRD.
I know its XRD but my question is different from this.

..Dr Naceur Selmane,
Sample is diamond single crystal.. JCPDS will work for the powder sample..
Thank you for answering ...
Dear Dr.Abhay Dasadia
The orientation of diamond crystal can be measured using SEM. The deep understanding of the crystals can be explored using Raman spectra and TEM tools.
The reference is below.
Hope it helps.

XRD is typically used to do it. I cannot see how you can check the crystal orientation by means of SEM. Ion channeling can be used to get some insight, but you need an Ion Beam (FIB source). Raman is another good option but the data analysis can be quite complicated. if you prepare your film on a well known (from the Raman point of view) substrate, you can extract the information you need.
You can use the X-ray Diffraction Analysis to Determine the Orientation of Single-Crystal Materials
If the solid sample can be partially melted and then crystal growth starts - some conclusion on its orientation can be made by observing the shape of the interface - dendrites or facets...
