Probing the electronic and structural properties of doped aluminum clusters: MAl12- (M=Li, Cu, and Au).
Photoelectron spectroscopy (PES) is combined with theoretical calculations to investigate the electronic and atomic structures of three doped aluminum clusters, MAl12- (M=Li, Cu, and Au). Well-resolved PES spectra have been obtained at two detachment photon energies, 266 nm (4.661 eV) and 193 nm (6.424 eV). Basin-hopping global optimization method in combination with density-functional theory c...
متن کاملQuench Rate Effects on the Natural Aging Behavior of 7xxx Al-mg-zn-cu Aluminum Alloys
The effect of quench rate on the natural aging behavior was examined using microhardness, conductivity and the differential scanning calorimeter. The data indicated that GPZ formed during extended natural aging of 7075, while extended aging of 7050 resulted in the precipitation of η’. Introduction The aluminum alloy system Al-Zn-Mg-Cu is the mainstay of aluminum alloys used in the aerospace ind...
متن کاملشبیهسازی و ساخت لایه‌های نانو ساختارZnS/Metal/ZnS و بررسی خواص ساختاری و اپتیکی آن‌ها
Conductive transparent ZnS/M/ZnS, (M = Au, Ag, Cu, Al) nano-structures have been simulated by optimization layers thickness, and gold, silver, copper, and aluminum materials were used as a metal layer and zinc sulfide for dielectric layers. Then the optimum simulated structure has been fabricated on a glass substrate by thermal evaporation. The crystallinity properties of the structures, such a...
متن کاملThin Al, Au, Cu, Ni, Fe, and Ta films as oxidation barriers for Co in air
We have investigated the effectiveness of Al, Au, Cu, Ni, Fe, and Ta films with thicknesses up to 4 nm for protecting a Co surface from oxidation in air at room temperature. The distinct change in the Co 2p3/2 core-level line shape observed by x-ray photoelectron spectroscopy upon the oxidation of Co makes it a simple matter to identify the fractions of the Co that are in the metallic state and...
