Band-Gap Engineering in Unconventional Semiconductors
Critical areas of contemporary society (e.g., biomedical imaging, quantum information transfer, and energy harvesting) rely on efficient detection and light generation. The overall aim of the project is, based on "optical bandgap engineering", the exploration of the best candidate materials for single-photon emitters working at room temperature in the near-infrared (NIR) range for optical fiber telecommunication and bioimaging. For this purpose, we are going to develop a consortium among the Japanese and V4 partners to undertake multidisciplinary joint research at a level and volume beyond the capabilities of any single member. Each member has complementary knowledge, skills, and experiences in terms of the types of advanced optical materials, spectroscopy, microscopy, and time-dependent/photon correlation measurements, working on individual work packages towards the same goal. Through multidisciplinary collaboration, advanced optoelectronic crystals, whose optical bandgap is controlled via crystal and defect engineering, can be realized. This is in line with the aim of the joint project, that is, to develop high-quality research networking to exchange existing knowledge and to pursue state-of-the-art science and technology through collaboration towards the realization of innovative and robust economies and societies in participating countries.
