Why TiO2 Is N Type Semiconductor?
Why TiO2 Is N Type Semiconductor? We may think about it like Oxygen vacancies indicate that there are 2 free electrons for every O atom missing from the structure. Hence, more free electrons exist in the d-orbitals (conduction band) resulting in making the TiO2 structure rich-in-electrons (n-type). Why is TiO2 a semiconductor? The oxygen vacancies
