Zinc oxide-based multilayer structural body and its producing method |
摘要 |
The present invention is effective for causing charge separation by complexing zinc oxide crystals in different states one another when a zinc oxide semiconductor is used as an electronic element. The present invention provides a zinc oxide-based laminated structure comprising two layers of a zinc oxide or zinc oxide solid solution layer with a lattice volume of Va and a donor concentration of Na, and a zinc oxide or zinc oxide solid solution layer with a lattice volume of Vb and a donor concentration of Nb, wherein the relationships of Va<Vb and Na>Nb being satisfied between both layers of the laminated structures; and the layer with the lattice volume Va serves as a charge-supplying layer and the layer with the lattice volume Vb serves as a charge-receiving layer in the laminated structure. The charge is transferred from the layer serving as the charge-supplying layer to the layer serving as the charge-receiving layer even when no external electric field is applied to the laminated structure; and a charge depletion layer is formed in the charge-supplying layer due to charge transfer from the charge-supplying layer to the charge-receiving layer.
