Photon Mapping of MgO thin Films with an STM
The light emission from an STM junction consisting of an MgO thin film on Mo(001) and an Au tip is analyzed with respect to its spatial distribution for various excitation conditions. The spectral characteristic of the light is compatible with an emission mechanism mediated by tipinduced plasmons that are excited by inelastic electron tunneling involving field emission resonances in the tip-sam...
متن کاملStructure and morphology of thin MgO films on Mo(001)
We report on the structural evolution versus thickness of MgO thin films grown epitaxially on Mo(001) and on the correlation between structure and surface morphology. The misfit strain induced by the mismatch with the substrate is relieved between 1 and 7 ML MgO due to the formation of an ordered network of interfacial misfit dislocations aligned along the MgO <110> directions, particularly evi...
متن کاملHRTEM and EELS study of Y2O3/MgO thin films.
Y2O3 thin films deposited on (001)-MgO substrate have been investigated by high-resolution transmission electron microscopy (HRTEM) and electron energy loss spectroscopy. Digital processing of the HRTEM images reveals the presence of grains with a crystallographic structure different from that of the rest of the film (Ia3). The spectrum imaging technique has been applied in vicinity of the Y2O3...
متن کاملBinding of single gold atoms on thin MgO(001) films.
In the present Letter the first electron paramagnetic resonance spectra of single metal atoms on a single crystalline oxide surface are presented. For Au atoms on a MgO(001) film investigated here an analysis of the angular dependent resonance positions and the hyperfine coupling to (17)O shows that the atoms are bound on top of oxygen ions on the terrace of the film. This result is in perfect ...
متن کاملCharacterization of surface defects on MgO thin films by ultraviolet photoelectron and metastable impact electron spectroscopies
Metastable impact electron spectroscopy ~MIES! and ultraviolet photoelectron spectroscopy are used in this study to investigate low-defect and defective MgO~100! thin films. Unlike low-defect films, defective films exhibit a new spectroscopic feature located ;2 eV above the top of valence band. Exposing the defective film to oxygen quenches the emission of electrons from F centers created on th...
