Measuring Electronic States Of Surfaces

Although the electronic states of a material‘s surface are only 2D, they contain a wealth of interesting physics. These states, which differ from the bulk of the material, dominate many phenomena, including electrical conduction, magnetism, and catalysis. They are responsible for nontrivial surface effects observed in topological materials and systems with strong spin-orbit interaction. Surface [..]
