ThresholdK-LLAuger spectra of P in InP

Abstract

The evolution of EC-L2 3L23 D2 radiationless resonant Raman scattering into Auger-electron emission was studied by tuning synchrotron radiation across the K edge of P in InP. The spectrum can be interpreted in terms of a two-component model that involves excitation of a photoelectron (1) into a discrete excitonlike state and (2) into the continuum; extra-atomic relaxation is taken into account. Auxiliary studies of above-threshold Auger and photoelectron spectra arising from K photoionization were used to identify the dominantly atomic features of these spectra.PACS number(s): 32.80.Hd, 32.80.Fb

Attosecond Electron Delocalization in the Conduction Band through the Phosphate Backbone of Genomic DNA

“…3(a), where spectator [ 1 D 2 t 2 and 1 S 0 t 2 ] and normal Auger peaks [( 1 D 2 ) and ( 1 S 0 )] are observed. The observed structure is assigned by comparison with normal Auger spectra above the P1s ionization potential and by comparison with previous measurements [15]. The spectator Auger feature is shifted to higher kinetic energy compared to the normal Auger feature because of the screening interaction of a core hole with the localized spectator electron.…”

Studies of fluorescence and Auger decay following inner-shell photoionization

“…In the solid state, changes in screening can be masked by conductionband electrons depending on specific characteristics of the material studied (see e.g. Drube et al, 1994;Wang et al, 1994).…”

Localization of electrons in the sugar/phosphate backbone in DNA investigated via resonant Auger decay spectra

“…21,22 It has been elucidated that the Auger peaks for insulator are split into two components, spectator and normal Auger peaks, and the most of the decay channels around the core-to-valence resonance excitation is spectator-type Auger decay. For semiconductors, the relative intensity of spectator-type Auger decay is small, 19 and for metals only a single Auger peak is observed. 22 In the case of FIG.…”
