Can anyone help me to draw the crystal structure of Al0.98Er0.02N and Al0.98Y0.02N ? I tried using both VESTA and CrsytalMaker, but I am always finding difficulties to insert Er and Y atoms in AlN hexagonal structure.

More information, please - how are you adding the Er and Y atoms? If you go into Edit > Structure, you can add the atoms by entering x y and z coordinates

@Laura : Firstly, I synthesized Al1-xErxOOH and Al1-xYxOOH by hydrothermal process, then it is nitridated in NH3 flow to obtained Al1-xErxN and Al1-xYxN. What I struggle of is the position of the doping atoms in AlN structure. I expect that Er and Y will subttitute Al site since those have same atom valency (+3).
