In the realm of oxide semiconductors, excitons play a pivotal role in defining their optoelectronic capabilities, crucial for applications in areas ranging from photonics to thermoelectric devices. Recent decades have seen significant developments in this field, particularly within wide-bandgap materials such as ZnO, Cu2O, and Ga2O3, among others. These advancements have facilitated the exploration of various excitonic structures, including neutral excitons, trions, and biexcitons, each contributing distinctively to the enhanced optical properties of these semiconductors.
This Research Topic aims to deepen the understanding of excitonic interactions within wide-bandgap oxide semiconductors, focusing on the multifaceted electron-phonon interactions and the complex dynamics of electron-hole pairs. A comprehensive analysis of how these interactions influence the material's optoelectronic properties will be pivotal, potentially paving the way for breakthroughs in next-generation device applications. Such insights will also facilitate the refinement of material synthesis and processing techniques to tailor excitonic properties more effectively.
