Dear prof. Abdelkader Hafdallah,

because of difference anterface energy between the ITO and FTO substrates, the structure of ZnO film will be different, especially at nano scale.

Dear khalid haneen ;

Thank you for you answer

I am agree with Dr.Khalid Haneen, additionally the method of formation thin film and the heat treatment.

Dear Dr. Suliman Elhadi,

the heat treatment very important factor for thin film properties

Dear prof.Hafdallah,

The difference may obviously come from the interface.Depending on the application you should consider the lattice mismatch ZnO/ITO or ZnO/FTO..

Dear Pr. Hafdallah,

I agree with Sarah's answer.
