The Group of Emerging Semiconducting Materials specializes in exploring the fundamental electronic structure and optical properties of novel semiconductor materials, including a broad family of 2D semiconductors, metal halide perovskites, and various types of van der Waals heterostructures. Our goal is to develop a deep understanding of these promising materials, which have the potential to revolutionize future technologies. Perovskites, for instance, show great promise for applications in solar cells and light emitters, while transition metal dichalcogenides (TMDs) are being actively studied for their potential in electronics, optoelectronics, and quantum computing. Beyond their technological applications, these materials offer a unique platform for investigating new physical phenomena that are absent in conventional semiconductors
Our research relies on advanced optical spectroscopy techniques, often combined with magnetic fields, to provide a comprehensive insight into the fundamental properties of these materials—particularly their excitonic behavior. This approach allows us to uncover key physical mechanisms that govern their performance and unlock new opportunities for future applications.
