An object of the invention is to provide an oxide thin film which exhibits a widegap or transparency and p-type conductivity although it has heretofore been very difficult to form. The oxide thin film formed on a substrate contains copper oxide and strontium oxide as a main component and exhibits p-type conductivity at a bandgap of at least 2 eV.

Предмет вымысла должен обеспечить пленку окиси тонкую exhibits проводимость widegap или транспаранта и п-tipa хотя heretofore очень трудно сформировать. Окись тонкая, котор пленка сформировала на субстрате содержит медную окись и окись стронция как главным образом компонент и exhibits проводимость п-tipa на bandgap по крайней мере eV 2.
