In optics and spectroscopy, the radiative Auger effect is a decay channel of an inner-shell atomic vacancy state, in which an X-rayphoton is emitted accompanying simultaneous promotion of an electron into either a bound or a continuum state. Thus the transition energy is shared between the photon and the electron.[1] The effect was first observed by Felix Bloch and Perley Ason Ross,[2] with the initial theoretical explanation by Bloch.[3]
Later the effect has also been observed on defects in the solid-state,[4] semiconductor quantum emitters,[5][6] as well as two-dimensional electron gases.[7][8] In the latter case, the effect is typically referred to as shake-up.
