Semiconductors and Semimetals series, highlights new advances in the field, with this new volume presenting interesting chapters. Each chapter is written by an international board of authors.

• 2019 marks the year that nitride ferroelectrics were reported, and the indicators and mechanisms used for oxide ferroelectricity appear inadequate
• The emergence of nitride ferroelectrics has opened new frontiers in ferroelectric materials research and ferroelectric based technologies. This book is a direct consequence of this
• Draws upon the collective knowledge and expertise of leading scientists and researchers in this field to provide a holistic view on the state of ferroelectric nitride research and applications
