Auger decay of 3p-ionized krypton

Single-molecule photochemical reactions of Auger-ionized quantum dots

Photoinduced electron transfer in donor-acceptor systems composed of quantum dots (QDs) and electron donors or acceptors is a subject of considerable recent research interest due to the potential applications of such systems in both solar energy harvesting and degradation of organic pollutants. Herein, we employed single-molecule imaging and spectroscopy techniques for the detection of photoche...

Three-electron collective Auger decay in CH3F

KLL Auger decay in free aluminum atoms

The KLL Auger transitions in free atoms present the simplest nonradiative electronic decay channel and therefore are of fundamental theoretical interest. Atomic spectra are advantageous for detailed theoretical analysis because the solid-state and molecular environments cause additional demands for the interpretation of spectra. Besides Ne 1,2 and Ar 3 rare gases, only the KLL spectra of Na 4 a...

Auger decay of the photoexcited 2pnl Rydberg series in argon

The 2pns(nd) inner-shell photoexcited resonance states in argon are studied using a combination of optical potential, multichannel quantum defect theoretical, and R-matrix methods. Optical potential inclusion of the infinite number of core decay channels correctly accounts, in an implicit manner, for the physical broadening of resonances within the 3p and 3s cross sections, but highly asymmetri...

Temperature dependence of exciton Auger decay process in Cuprous Oxide

We report theoretical and experimental study on Auger decay of excitons in Cu2O in a wide range of temperatures, from 2 Kelvin to 325 Kelvin, in single-photon surface excitation. We find that the Auger constant linearly increases with temperature above 100 Kelvin. This constant is important for experiments on Bose condensation of excitons.
