Spray pyrolysis method was used to accumulate zinc oxide layers in order to pollute them and to obtain P-type conductivity," Golshani said, adding, "In this method, which is usually classified in chemical accumulation methods, raw materials (salts which contain final elements) are dissolved in solvents such as methanol, ethanol, water, etc, and constitute the initial material.
9] [ohm]cm), and with slightly p-type conductivity, on the other hand, an excess of Cd atoms located interstitially can produce n-type CdTe samples.
It is also known that the CdTe structure in these samples contains Cd vacancies, which account for the p-type conductivity and therefore, making it difficult for the n-type doping of this material.
The origin of p-type conductivity in these transparent oxides receives considerable attention, and field emission properties and nanostructured materials are discussed.
