The evolution of Si 2p core-level photoemission during a structural conversion from the Si (1 1 1)–
-Ag to the Si(1 1 1)–
-Ag superstructures induced by Ag adatoms adsorption at 140 K was studied using synchrotron radiation. The component from the top-layer Si-trimer atoms on the former surface was found to split into two components in the latter surface. The result is discussed in terms of a relaxation in some of the Si trimers induced by Ag adatoms sitting on the nearby Ag triangles of the
-Ag substrate. The intensity ratio between the split components is a key to exclude some structure models proposed so far for the
phases. 相似文献

It was found that the packing of cations and anions influences the electronic structures of mixed-valence binuclear ferrocene derivatives. Temperature-dependence of the mixed-valence state of 11, 1111-diisobutylbiferrocenium triiodide was observed in a crystalline state, whereas only a trapped-valence state was found in a dispersed state. The packing effect was also observed for a series of 11, 1111-dialkyl- and 11, 1111-bis(methylbenzyl)biferrocenium triiodides by means of ESR spectroscopy. 相似文献

Ion irradiation effects on improvement of flux-pinning properties for quenched and melt growth YBCO samples (QMG-materials)
were studied. Irradiation with 16MeV protons was performed up to a dose of 1×1016 p/cm2. The effective activation energies of vortices are expressed with the formula, Ueff=g(T)h(H)f(J) ∝ (J/Jc)−∝* [1-(T/Tx)2]2/3*H−1/3 at lower irradiation doses below 5×1015 p/cm2. The J-dependence of Ueff changes from power-law to quesi-exponential dependence with an increment of irradiation dose. 相似文献

The phase diagram and the heat of transition of AgI-AgBr system have been determined by using the differential scanning calorimetry (DSC) with the help of X-ray diffraction patterns. It has been verified that the miscibility gap between β-AgI-type solid solution and AgBr-type one depends on the thermal history of the sample. From the thermodynamic point of view, it is likely that the variation of transition temperature with composition suggests the change of correlation among silver ions in superionic conducting phase. 相似文献
