What do yuo mean "tolerance factor"?

Thanida (Sureeporn) Pollaor

Dear sir,

I kinda indicator to determine the distortion degree of lattice by impurity. See publication in attached file.

Best regards,

Lior Kornblum

As far as I know the (Goldschmidt) tolerance factor applies only to ABO3-type unit cells.

Dear Lior,

How about ZnO? Is there any method to determine the magnitude of dopant?

I'm not sure I understand the question. Are you trying to determine the concentration of a dopant?

IDear Sureeporn,

I think Lior is right. I can not imagine a way to use the tolerance factor in ZnO according to the definition given in the attached paper. What will the ionic radii r_a and r_b be in ZnO? On the other hand, if you want to know how the structure change upon doping, I think there are plenty of papers describing that.

Dear All,

I did 3 different dopant and co-doping then I need to order the magnitude of dopant in order to make a conclusion about the lattice, strain and optoelectronic properties of ZnO. As well as show the efficiency of co-doping method. Now I found out that the variation of aspect ratio gives me the reasonable order which is in agreement with literature but I still need some parameter that can quantify the degree of dopant toward ZnO lattice structure.
