TENSILE TESTING OF FREE-STANDING Cu, Ag AND Al THIN FILMS AND Ag/Cu MULTILAYERS
ÐFree standing polycrystalline thin ®lms with a strong h111i texture were tested in uniaxial tension. Studied were electron-beam deposited Ag, Cu and Al ®lms, and Ag/Cu multilayers consisting of alternating Ag and Cu layers of equal thickness, between 1.5 nm and 1.5 mm (bilayer repeat length, l, between 3 nm and 3 mm). The ®lms had a total thickness of about 3 mm. A thin polymeric two-dimension...
متن کاملBurrowing of Co nanoparticles on clean Cu and Ag surfaces
Metal nanoparticles can display a unique behavior when deposited on substrates with a significantly lower surface energy. Co nanoparticles in the 10 nm size regime burrow into clean Cu(100) and Ag(100) substrates when deposited at 600 K and also assume the substrate orientation. Deposition at room temperature fails to show either burrowing or reorientation. Crucial in understanding these result...
متن کاملLow-Temperature Synthesis of Anatase TiO2 Nanoparticles with Tunable Surface Charges for Enhancing Photocatalytic Activity
In this work, the positively or negatively charged anatase TiO2 nanoparticles were synthesized via a low temperature precipitation-peptization process (LTPPP) in the presence of poly(ethyleneimine) (PEI) and poly(sodium4- styrenesulfonate) (PSS). X-ray diffraction (XRD) pattern and high-resolution transmission electron microscope (HRTEM) confirmed the anatase crystalline phase. The charges of t...
متن کاملDefect chemistry, surface structures, and lithium insertion in anatase TiO2.
Atomistic simulation techniques are used to investigate the defect properties of anatase TiO(2) and Li(x)TiO(2) both in the bulk and at the surfaces. Interatomic potential parameters are derived that reproduce the lattice constants of anatase, and the energies of bulk defects and surface structures are calculated. Reduction of anatase involving interstitial Ti is found to be the most favorable ...
متن کاملInvestigation of the Statistical surface morphology and optical properties of the Ag/Al and Ag/Cu thin double-layers
In this work, thin films were deposited on the amorphous glass substrates by magnetron sputtering method. Surface morphology of double-layers of Ag/Al and Ag/Cu were investigated. For surface morphology studies atomic force microscope (AFM) and scanning electron microscopy (SEM) were used, variations of the grain and partical size as well as surface roughness, roughness exponents and correlatio...
