One way is to form pellet out of the synthesized nanoparticles and perform hall-effect characterization

S. Mostafa Hosseinpour-Mashkani

Is there any easy way?

Tasnim Kamal @

In our case we have followed two methods, one was the above mentioned process and other was using BURAI software. Creating supercell structure and measuring vacancy properties. This is more difficult and analytical though.
