“…This information is directly accessible with GIFAD because the incident atom probes the valence electron density above the surface, whereas X-Rays as well as electrons explore electron densities much closer to the atomic cores. This electron rearrangement has been observed experimentally [13] and later on confirmed theoretically [14].…”

“…The ratio of Se 3d/Zn 3d core-level intensity changes as a function of the annealing temperature from 100 to 500°C and was previously described also associated with reconstruction of the ZnSe͑001͒ surface. 26 By further increasing the annealing temperatures above 380°C the Zn 2p signal reappears with an additional shift of 0.5 eV to higher binding energy, and a 33% increase in the linewidth ͑full width at half maximum͒ relative to the initial residual signal. The integrated intensity of the Zn 2p 3/2 FIG.…”

We report the chemical stability of the hybrid Fe/ZnSe/GaAs heterostructure prepared by molecular-beam epitaxy. Analyses of photoemission spectra show a remarkable chemical stability of the Fe/ZnSe(001) interface up to 380 °C, where the effective disruption of the heterostructure occurs, together with the appearance of Ga atoms near the film surface. This suggests that the ZnSe/GaAs interface is surprisingly less stable than the Fe/ZnSe one.

“…[37][38][39][40] This is also the case for the decomposition of the Cd 4d core level in CdSe. Although the Lorentzian function is rather on the broad side of the linewidths found in the literature, a single component fully describes the measured spectrum.…”

Phase transformation of PbSe/CdSe nanocrystals from core-shell to Janus structure studied by photoemission spectroscopy

et al. 2013

Photoelectron spectroscopic measurements have been performed, with synchrotron radiation on PbSe/CdSe heteronanocrystals that initially consist of core-shell structures. The study of the chemical states of the main elements in the nanocrystals shows a reproducible and progressive change in the valence-band and core-level spectra under photon irradiation, whatever the core and shell sizes are. Such chemical modifications are explained in light of transmission electron microscopy observations and reveal a phase transformation of the nanocrystals: The core-shell nanocrystals undergo a morphological change toward a Janus structure with the formation of semidetached PbSe and CdSe clusters. Photoelectron spectroscopy gives new insight into the reorganization of the ligands anchored at the surface of the nanocrystals and the modification of the electronic structure of these heteronanocrystals.
