Abstract
The present invention provides a low-resistivity p-type single-crystal zinc oxide. An n-type dopant and p-type dopant are doped into zinc oxide with higher concentration of the p-type dopant than that of the n-type dopant during forming a single-crystal of the zinc oxide through a thin film forming process. Further, an element of the second group is co-doped to allow oxygen to be stabilized.
