1. Brief introduction

III-Nitrides semiconductors, their compounds and nanostructures are very fascinating systems due to their intriguing fundamental properties leading to interesting applications in various fields (photovoltaics, solid state lighting, high frequency electronics). This issue provides a valuable contribution to this field as it integrates experimental and theoretical approaches, and presents an overview of different aspects of III-N structures: growth-related problems, defects analyses, advanced characterization methods, and the discussion of electronic, structural and vibrational properties. We hope that this special issue contributes to a more general understanding about the fundamental aspects of III-Nitride nanostructures by presenting the state of the art in this field to the broad community of materials scientists.
