SUMMARY
Valley degrees of freedom refer to the local minima or maxima present in the valence and conduction bands of semiconductors. These valleys represent distinct energy states that electrons can occupy, influencing the electronic properties of materials. Understanding valley degrees of freedom is crucial for advancements in semiconductor technology, particularly in the development of valleytronics, which exploits these valleys for information processing.
