Local Density of States

The Local Density of States (LDOS) describes how many electronic energy levels are available at a specific location within a material. Think of it as a map showing where electrons can exist and how likely they are to be found at particular energies nearby. LDOS helps scientists understand how electrons behave in different parts of a material, especially at surfaces, interfaces, or around impurities. It is a crucial concept in condensed matter physics and nanotechnology, providing insight into electrical, optical, and magnetic properties of materials at very small scales.
