I need to dope metal to my metal oxide matrix, Can anyone clearly explain me about the calculations that i need to workout for mol %.
Dear Armanath,
lets try an example. We want to dope 1 mol Ga2O3 with 1mol% Si.Therefore we need the atomic weights of the constitutions. We use rounded values: For Ga 70, for O 16 and for Si 28.
1 mol Ga2O3 gives 2*70g + 3*16g = 188 g/mol.
1mol% Si gives 0,01*28g = 0,28 g/mol.
Now it is important to say, what you want to know. First, what Jafar wrote, do you substitute Ga or add Si (for instance by implanting among lattice sites). Second:
What you want really know. A mol-concentration gives here no sense. Better you calculate the mass portion.
Lets in our example calculate the mass concentration of Si x after adding 0,28g Si into the matrix:
x = (0,28/28)/(0,28/28 + 1)=0,0099 or 0,99%
But it is important exactly to say, what you have and what you want to get.
Furthermore, you can calculate mass- , volume-, mol- and particle concentrations.

please tell about material and metal to be doped and also let me know is it subsitution or doping?
