Density distribution of states

In solid state physics and condensed matter physics, the density of states (DOS) of a system describes the number of modes per unit frequency range. The density of states is defined as $${\displaystyle D(E)=N(E)/V}$$, where $${\displaystyle N(E)\delta E}$$ is the number of states in the system of … See more In quantum mechanical systems, waves, or wave-like particles, can occupy modes or states with wavelengths and propagation directions dictated by the system.
