QUANTUM WELL STRUCTURE AND SEMICONDUCTOR DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a quantum well structure composed of an oxide with a high-potential corundum structure, and to provide a semiconductor device including the quantum well structure.SOLUTION: Provided is a quantum well structure in which a first layer, and a second layer whose main component is a material different from that of the first layer are alternately laminated at least one by one. The main component of the first layer is an oxide having a corundum structure, and the main component of the second layer is a material having a corundum structure. Also provided is a semiconductor device including the quantum well structure.SELECTED DRAWING: Figure 3
