Question

What is the significance for chemical potential plot for czts?

Answer 1

The conduction type whether it is n orp depends on the chemical bond configuration dominating in the structure after deposition and post annealing if any. So, crystallographic defects in the materials and the addition of impunity atoms controls the conduction type. Stoichiometry can play a role in the conduction type.

So, microscopic investigations are required to determine the specific cause.
