摘要: Provided is a ZnO-based semiconductor device capable of growing a flat ZnO-based semiconductor layer on an MgZnO substrate having a main surface on the lamination side oriented in a c-axis direction. ZnO-based semiconductor layers 2 to 6 are epitaxially grown on an MgxZn1-xO (0≦x≦1) substrate 1 having a +C surface (0001), as a main surface, inclined at least in an m-axis direction. A p-electrode 8 is formed on the ZnO-based semiconductor layer 5, and an n-electrode 9 is formed on the underside of the MgxZn1-xO substrate 1. Thereby, steps regularly arranged in the m-axis direction can be formed on the surface of the MgxZn1-xO substrate 1, and a phenomenon called step bunching is prevented. Consequently, the flatness of a film of the semiconductor layers laminated on the substrate 1 can be improved.

摘要: To solve the foregoing problems, provided is a ZnO-based semiconductor element having an entirely novel function distinct from hitherto, using a ZnO-based semiconductor and organic matter for an active role. An organic electrode 2 is formed on a ZnO-based semiconductor 1, and an Au film 3 is formed on the organic electrode 2. An electrode formed of a multilayer metal film including a Ti film 4 and an Au film 5 is formed on the back surface of the ZnO-based semiconductor 1 so as to be opposed to the organic electrode 2. A bonding interface between the organic electrode 2 and the ZnO-based semiconductor 1 is in a pn junction-like state. Thus, rectification occurs therebetween.

摘要: Provided are a ZnO-based thin film and a ZnO-based semiconductor device which allow: reduction in a burden on a manufacturing apparatus; improvement of controllability and reproducibility of doping; and obtaining p-type conduction without changing a crystalline structure. In order to be formed into a p-type ZnO-based thin film, a ZnO-based thin film is formed by employing as a basic structure a superlattice structure of a MgZnO/ZnO super lattice layer 3. This superlattice component is formed with a laminated structure which includes acceptor-doped MgZnO layers 3b and acceptor-doped ZnO layers 3a. Hence, it is possible to improve controllability and reproducibility of the doping, and to prevent a change in a crystalline structure due to a doping material.

摘要: Provided are an oxide thin film doped with an n-type impurity, and an oxide thin film device. In an oxide thin film (2), as shown in FIG. 1(b), doped oxide layers (2a) doped with an n-type (electron-conductivity type) impurity and undoped oxide layers (2b) not doped with an n-type impurity are laminated in an alternating and repeated manner. When an oxide layer is doped with the n-type impurity at a high concentration, roughness of a surface of the oxide layer becomes large. For this reason, the doped oxide layers (2a) are covered with the undoped oxide layers (2b) capable of ensuring surface flatness, before surface roughness attributable to the doped oxide layers (2a) becomes very large. Thus, a flat oxide thin film can be formed.
