Metastable Impact Electron Spectroscopy

The Metastable Impact Electron Spectroscopy (MIES) is a method to study the surface of solids .

In MIES, helium atoms, which are in a metastable electronic state, are shot at a surface. The interaction of the helium with the surface leads to the emission of electrons . Their analysis allows conclusions to be drawn about the electronic structure of the surface, such as the electronic density of states .

MIES is a surface-sensitive method, as the helium atoms only interact with the top layer of the surface, and requires the use of an ultra-high vacuum .
