   Inverse Photoemission (IPE)
   IPE is the time-reversal of photoemission. An electron of specific kinetic energy strikes a material surface and transitions to a lower, unoccupied energy level, emitting a photon. This process is critical for mapping empty electronic states (conduction bands) and is highly sensitive to the surface density of transient, [polarized vacancies](/ent…
