Dear all,
Hi, I am looking for a non-destructive method of determining the crystal orientation of a smaller-than-50x50x50 μm single crystal, mounted on a quartz substrate.
I've considered several x-ray methods like Laue method, or microfocused XRD, but there are some experimental difficulty when using x-ray methods because the crystal is placed on a quartz substrate. Quartz substrate is amorphous (made with fused quartz glass) and it most likely adds very broad peak background to the measurement, which would be terrible in cases where strong diffraction peaks are hard to obtain for crystals such as very small ones I mentioned above.
Optical methods (optical crystallography) might work when polarized microscopes are used. However, some samples I am looking at are triclinic, meaning none of the crystallographic axis could match the optical axis.
EBSD will obviously not work because I need to put them in SEM with electron beam that can kill the material.
Can anyone suggest me a good method?EDIT: Crystallographic information file is already available obtained previously by single crystal x-ray.Thank you.(Note to the moderators: I was not sure if I should put this in this general physics forum or atomic and condensed matter forum. If this place is inappropriate, please move the thread. Thank you.)
