'''Density of states''' quantum density of states describes how many quantum states are available within a given energy interval. Quantum density of states describes how many quantum states are available within a given energy interval. The density of states is a counting function in energy space. It becomes useful when individual quantum levels are so closely spaced that the spectrum can be treated as effectively continuous. In confined systems, boundary conditions restrict wavefunctions to discrete standing-wave solutions. As the size of the system increases, these discrete levels become densely packed, and a continuous density-of-states description becomes appropriate. In the free-electron model, electrons are treated as particles in a three-dimensional box.
