The electrical properties of zinc oxide

What is the electrical properties of zinc oxide? At room temperature, zinc oxide, the band gap of 3.3 eV as a result, the pure zinc oxide is a colorless transparent. High band gap of zinc oxide with high breakdown voltage, maintain a strong electric field, high power electronic noise is small, affordable, etc. A percentage of magnesium oxide or cadmium oxide, zinc oxide with can make the band gap change between 3-4 eV.

Zinc oxide even without adding any other matter, also has the characteristics of n-type semiconductor. N-type semiconductor features have been considered with compound atoms of whole than sexual, while the study of pure zinc oxide as an example. Using aluminum, gallium, indium, including group III or chlorine, iodine and other halogen can adjust the n-type semiconductor performance. And to make zinc oxide as P type semiconductor has certain difficulty. Available additives including alkali metal element such as lithium, sodium, potassium, nitrogen, phosphorus and arsenic gan V main group elements, copper, silver and other metals, but need to be under special conditions is the utility.
