what is the essentail difference between local density of states and density of state?
It is very difficult to figure it out

The local density of states (LDOS) refers to the density of electronic states at a specific point in space, while the density of states (DOS) refers to the overall density of electronic states in a material. In other words, LDOS gives information about the electronic states at a specific location, while DOS gives information about the electronic states throughout the entire material.
Both LDOS and DOS can be measured using various experimental techniques, such as scanning tunneling microscopy (STM) or photoemission spectroscopy. These techniques allow scientists to map out the energy levels and spatial distribution of electronic states in a material.
The local density of states and density of states are influenced by several factors, including the electronic band structure of the material, the atomic and molecular structure, and external factors such as temperature and pressure.
The local density of states and density of states are closely related, as they both provide information about the electronic states in a material. The LDOS can be integrated over all energy levels to obtain the DOS, and the DOS can be used to calculate the LDOS at a specific energy level.
The local density of states and density of states are important for understanding the electronic properties of materials, which is crucial in various fields such as materials science, condensed matter physics, and nanotechnology. They can also provide insight into the behavior of electrons in different environments and how they interact with each other. This information is essential for developing new materials and improving existing technologies.
