Photoemission Electronic Spectra οf CdTe/Pb0.95Eu0.05Te/CdTe

Sharp photoemission spectra in the quantum antiferromagnet.

The low energy photoemission spectra in quantum antiferromagnets are studied by using several approximation-free calculations and rigorous theorems. The important and measurable property found is that the hole eigenstates with momenta differing by the antiferromagnetic wavevector Q are equivalent and degenerate in energy. However the corresponding eigenstates differs by the presence or the abse...

Electron spectra of a self-assembled monolayer on gold: Inverse photoemission and two-photon photoemission spectroscopy

Ultraviolet photoemission spectroscopy, inverse photoemission spectroscopy, and two-photon photoemission spectroscopy are techniques commonly used to examine the electronic structure of surfaces and interfaces. We have used all three to study self-assembled monolayers of 4,4 0-bis(phenylethynyl)benzenethiol on gold, a system often studied for potential application in molecular electronic juncti...

The angle-resolved photoemission spectra of uranium based ferromagnets

We investigate the spin-split and magnetization dependence of the 5f angle resolved photoemission spectra. For large values of the spontaneous magnetization, the model supports magnetic polaron excitations. We compare the results of our calculations with recent experimental results of Durakiewicz, Joyce and co-workers on related 5f compounds.

Cooper minima in the photoemission spectra of solids.

Variations of the photoionization cross section of valence states as a function of interatomic distance are studied by means of atomic and solid-state density functional approaches and compared with photoemission data. In contrast to the free atom case, a series of Cooper minima is found for 4d, 5d, and 5f states in Pd, Ag, Au, and U metals. The discovered fundamental phenomenon is of high impo...
