Description: This special edition is devoted to the identification, characterisation, and understanding of the effects of structural critical imperfections of silicon carbide during bulk crystal growth and epitaxial deposition. Emphasis is placed on advanced analytical techniques that provide essential insight into the origin, distribution, and evolution of defects, enabling continuous improvement in crystal growth processes and epitaxial technologies. The publication aims to provide researchers and engineers with a deeper understanding of defect formation and characterisation, which is fundamental to achieving the material perfection required for the creation of reliable and efficient SiC-based electronic devices.
