HIGH RESISTANCE ZINC OXIDE SINGLE CRYSTAL AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a zinc oxide single crystal for various devices where Li concentration is extremely low and resistivity is high. SOLUTION: The desired zinc oxide single crystal is obtained by using a raw material 26 not containing Li substantially and a mineralizer solution and by a hydrothermal synthesis under the existence of a peroxide and at a high partial pressure of oxygen. At least one or more kinds of peroxides represented by hydrogen peroxide are added into the mineralizer solution by 0.02-0.5 mole/L in terms of oxygen generated by decomposition.
