Investigation Of Sodium And Potassium Doped P-Type Zinc Oxide Films
In this thesis, P-type zinc oxide (ZnO) films doped with sodium (NZO) and potassium (KZO) were fabricated on glass substrates using the sol-gel spin-coating technique. The P-type dopants were varied between 0 at.% and 25 at.%. A comprehensive correlation of surface morphology, structural, optical an...
