What is bottom energy?

Bottom energy refers to the potential energy of the lowest occupied electronic states in a solid or material. It is also known as the ground state energy. The electronic structure of a material determines its bottom energy, and it can be influenced by factors such as chemical composition, crystal structure, and temperature. The bottom energy of a material plays an important role in its physical properties, such as conductivity, magnetism, and optical properties. Understanding and controlling bottom energy is crucial for the development of new materials with specific properties for various applications.
