Low-dimensional materials such as carbon nanotubes, graphene, boron nitride (hBN), and transition metal dichalcogenides (TMDs) have provided an attractive platform for exploring new science at the nanoscale. In recent years, significant progress has been made in the development of two-dimensional (2D) systems, which have become a major focus in materials science, encompassing both fundamental principles and practical applications. This is due to the fascinating physical properties of individual 2D materials, as well as their potential as fundamental components for various nanostructures, including heterojunctions, heterostacks, and superlattices. Based on this background, we have been studying the fabrication of various low-dimensional superstructures, especially two-dimensional semiconductor-based heterostructures, using thin-film growth techniques (metal-organic chemical vapor deposition (MOCVD) and molecular beam epitaxy (MBE)) and dry transfer methods [1]-[6]. In addition to serving as an excellent platform for creating various quantum functions, these heterostructures can also be utilized in electronic device applications, which is the focus of this symposium. In this presentation, I will discuss our recent results on the fabrication of heterostructures and explore their properties. I will also provide a brief overview of the advancement of two-dimensional materials into electronic devices.
