high-temperature stability. In recent years, research and development of next-generation power devices using these materials has made significant progress. However, due to their strong covalent bonds, crystal growth is difficult, resulting in a high density of lattice defects such as dislocations in the grown crystal. Because some lattice defects impair device performance and reliability, it is crucial to accurately characterize the defect distribution and type, identify killer defects that significantly degrade device
characteristics, and feed this information back into crystal growth and device fabrication. This presentation focuses on the development of crystal characterization techniques for wide-gap semiconductors, explaining the fundamental principles and examples of these
techniques. We will explain the scope and challenges of each technique and introduce the latest evaluation examples, including synchrotron X-ray topography, etch-pit methods, transmission electron microscopy (TEM), and multiphoton excitation microscopy, as part of our efforts to develop new methods. *This seminar will be live-streamed using the video conferencing tool “Zoom” on the day of the event.
