[sdpd] random orientation in flat plates nanocrystallites

["Guilhem Dezanneau" <gdezano...@inpg.fr>]

Hi,
 
I have a problem to solve the determination of flat plate nanocrystallite dimensions.
Indeed, conversely to classical cases, my crystallites consist of flat plates (roughly 
30nm*200nm*200nm) but with a randomly distributed crystallographic orientation. While isotropic
grain size model works quite well, i  would like to correlate the value of crystallite size i obtained to the
lower dimension of my crystallites.
 
Do you know method to do that i.e. to determine the width of peaks for such crystallite shape with a orientation
not linked to crystal shape.
 
This problem drives me crazy....
 
Many thanks
