In this case, each specific layer in which a sufficient carrier concentration of 1×1018 cm−3 or more is obtained when a single layer is inserted at suitable intervals. As a result, a sufficient hole concentration of 1×1017 cm−3 or more is obtained in the overall crystal in a material in which a hole concentration smaller than 1×1017 cm−3 has been only conventionally obtained.
