QUANTUM WELL STRUCTURE OF USING ENERGY BAND CONTROLLED AND METHOD OF FORMING THE SAME

摘要

PURPOSE: A quantum well structure with a controlled energy band and a forming method thereof are provided to implement different band gaps in a well layer of a single structure. CONSTITUTION: A first barrier(110) is formed on a substrate(100). A well layer(120) is formed on the first barrier layer and includes a first region(121) and a second region(123) with different band gaps. A second barrier layer(130) is formed on the well layer. A dielectric thin film layer(140) is formed on the second barrier layer.
