The potentially extractable information carried by photoelectron spectromicroscopy data is analyzed. The results are used into finding practical optimization rules for different types of photoemission spectroscopy, microscopy, and spectromicroscopy experim ...
The combination of photoemission spectroscopy and high lateral resolution is rapidly evolving from feasibility tests to experiments. We discuss several important recent developments and results. ...
A first-principles investigation of Si 2p core-level shifts at the Si(001)-SiO2 interface is presented. We introduce several relaxed interface models obtained by attaching different crystalline forms of SiO2 to Si(001). These model structures contain the m ...
We have determined equilibrium geometries and electronic properties of neutral and anionic Cu-n (n = 2,9) clusters by means of first principles calculations in which s and d electrons are treated on equal footing. We find that the calculated electronic den ...
Photoelectron energy distribution spectra taken for the first time on micrometer-sized areas of cleaved GaAs(110) reveal rigid shifts from location to location in the photoemission core level peak energies, indicating band-bending changes on a microscopic ...
Neuron networks have been imaged with the scanning photoelectron microscope MAXIMUM, showing details in the submicron range such as axons, dendrites and their synapses. These results, obtained with the scanning photoemission microscope MAXIMUM, demonstrate ...
Core-level photoemission peaks taken on several insulators with spatial resolution of 30-300 mu m rigidly shift in energy from place to place, most likely because of local charging effects. Such phenomena can affect the linewidth and the general lineshape ...
Photoemission spectroscopy now reaches a lateral resolution in the submicrometer range. It is possible, therefore, to perform chemical analysis in the microscopic domain required for life-science experiments. We present a successful test of this approach, ...
A comparative study has been made of iodine-intercalated Bi2Sr2Ca1Cu2Ox single crystal and 1 atm O2 annealed Bi2Sr2Ca1Cu1Ox single crystal using an AC susceptibility measurement, X-ray photoemission (XPS) and angle-resolved ultraviolet photoemission spectr ...
The feasibility of creating homojunction band discontinuities by dipole intralayers was recently demonstrated with photoemission studies. We explored the nature of this intriguing mechanism by studying the effects of several complex intralayers, specifical ...
