摘要：
The development and characterization of nitride QW structures grown by atomic layer epitaxy (ALEp) for device applications are discussed. We have grown epitaxial thin films (4-10nm) covering the full range of binary and ternary III-N compositions by ALEp. In this work, ALEp-grown QW structures are presented. Optical characteristics are discussed. Characterization of layer interfaces and composition are critical to the development of this growth technique for quantum-based devices. Structures to study this by atom probe tomography have been created. By understanding the structure of crystalline ALEp films with nanometer-scale thickness, the unique properties of these materials can be advanced for quantum-scale applications.
