Core-level x-ray photoemission on NiO in the impurity limit

We present a core level X-ray photoelectron spectroscopy study of NixMg12xO crystals with 0.03,x,1. We show that nonlocal effects involving inter-Ni-site fluctuations strongly influence the Ni 2p core-level spectra for higher Ni concentrations including NiO itself. It is only in the very dilute Ni limit that the core-level spectra can be described in terms of an Anderson impurity model which al...

Surface core-level shifts on clean Si(001) and Ge(001) studied with photoelectron spectroscopy and DFT calculations

Surface core-level shifts on clean Si(001) and Ge(001) studied with photoelectron spectroscopy and DFT calculations, 2010, Physical Review B. The Si 2p and Ge 3d core levels are investigated on the c͑4 ϫ 2͒ reconstructed surfaces of Si͑001͒ and Ge͑001͒, respectively. Calculated surface core-level shifts are obtained both with and without final state effects included. Significant core-level shifts are...

Temperature Dependence of Magnetically Active Charge Excitations in Magnetite across the Verwey Transition.

We study the electronic structure of bulk single crystals and epitaxial films of Fe_{3}O_{4}. Fe 2p core level spectra show clear differences between hard x-ray (HAX) and soft x-ray photoemission spectroscopy (PES). The bulk-sensitive spectra exhibit temperature (T) dependence across the Verwey transition, which is missing in the surface-sensitive spectra. By using an extended impurity Anderson...

Electronic structure changes across the metamagnetic transition in FeRh via hard X-ray photoemission.

Stoichiometric FeRh undergoes a temperature-induced antiferromagnetic (AFM) to ferromagnetic (FM) transition at ~350 K. In this Letter, changes in the electronic structure accompanying this transition are investigated in epitaxial FeRh thin films via bulk-sensitive valence-band and core-level hard x-ray photoelectron spectroscopy with a photon energy of 5.95 keV. Clear differences between the A...

Deconvoluted Si 2p Photoelectron Spectra of Ultra thin SiO2 film with FitXPS method

The main impetus for our research is provided by the growing interest worldwide in ultra thin silicon dioxide on silicon based nano devices. The obvious need for better knowledge in the ultra thin gate silicon dioxides, is motivated both by interests in fundamental research and phenomenology as well as by interests in possible applications, which can be found with better fitting of experimental...
