The density of states (DOS) in physics and materials science quantifies the number of different states at a particular energy level that electrons are allowed to occupy in a system. It plays a critical role in determining the electronic properties of materials, influencing phenomena such as conductivity and band structure behavior.

In physics, an energy level refers to the fixed energies that a quantum system such as an atom, electron, or nucleus can have. These discrete energy levels play a critical role in determining the chemical and physical properties of matter, influencing how atoms bind with each other and interact with electromagnetic radiation.
