Valence electron photoemission spectrum of semiconductors: ab initio description of multiple satellites.
The experimental valence band photoemission spectrum of semiconductors exhibits multiple satellites that cannot be described by the GW approximation for the self-energy in the framework of many-body perturbation theory. Taking silicon as a prototypical example, we compare experimental high energy photoemission spectra with GW calculations and analyze the origin of the GW failure. We then propos...
متن کاملSpin-resolved photoemission of valence-band satellites of Ni
Spin-resolved photoemission spectra of 6-, 9-, and 13-eV satellites of the ferromagnetic Ni valence band are reported. The spin polarization of the valence-band satellites and their photon energy dependence are interpreted by the multiplet configuration of 3d and 3d final states. This implies the localization of a photoexcited final state reflecting the strong electron correlation in Ni. @S0163...
متن کاملGas-phase valence-electron photoemission spectroscopy using density functional theory.
We present a tutorial overview of the simulation of gas-phase valence-electron photoemission spectra using density functional theory (DFT), emphasizing both fundamental considerations and practical applications, and making appropriate links between the two. We explain how an elementary quantum mechanics view of photoemission couples naturally to a many-body perturbation theory view. We discuss ...
متن کاملValence photoelectron spectrum of KBr: Effects of electron correlation
The valence photoelectron spectrum has been measured for molecular KBr. Experimental energies of the main and satellite structures have been ompared with the results of ab initio calculations based on molecular orbital theory including configuration and multiconfiguration interaction pproaches. Comparison between the experimental KBr spectrum and previously reported Kr valence photoelectron spe...
متن کاملOscillations in the valence-band photoemission spectrum of the heterofullerene C59N: A photoelectron interference phenomenon
The intensities of the two strongest low-binding energy features in the valence-band photoemission spectra of C59N have been observed to oscillate as the photon energy of the exciting radiation is varied. The maxima in the intensity ratio of the two peaks occur at the same photon energies as the maxima in the intensity ratios of the highest occupied molecular orbitals to next highest occupied m...
