Formulation and optimization of a zinc oxide nanoparticle ...

A slightly reduced form of the oxide contains oxygen vacancies, with the extra electrons associated with shallow donor states near the bottom of the conduction band. This renders pure zinc oxide as an ntype semiconductor. A variety of techniques are available for synthesis of pure and doped zinc oxide and depositing them on different substrates,
