Status:

base class, extends NXobject

Description:

Total electron yield (TEY) mode XAS. The drain current or total ...

Total electron yield (TEY) mode XAS. The drain current or total electron current is proportional to the absorption coefficient:

\[\mu(E) \propto I_{ey}/I_0\]

TEY is inherently surface-sensitive because electrons are readily absorbed by most materials, limiting the probing depth to a few nanometers.
