We study the deposition of Ag ions, and size selected Ag/sub 7/ and Ag/sub 19/ cluster ions on Pd(100) at total kinetic energies of 20 eV and 95 eV using thermal energy atom scattering and molecular dynamics simulations. We find that at all energies Ag ato ...
All-fiber optical phase modulators were fabricated by coating standard telecommunication optical fibers with thin films of piezoelectric ZnO. Piezoelectric optical fiber coatings of PbZrxTi1-xO3(PZT) were also produced, and the actuation capability necessa ...
Particle contamination formed in reactive plasmas imposes an upper limit on the rate for particle-free deposition. Conversely, these plasmas could be exploited to produce nanometric clusters and particles for various applications. Infrared absorption spect ...

Electronic device-quality Cu was deposited on Pt-patterned oxidized Si wafers from hexafluoroacetylacetonate-copper(I)-trimethylvinylsilane by using low-pressure chem. vapor deposition at 150-250 Deg in He carrier gas. Smooth Cu films ?0.8 mm thick have be ...
We study the deposition and the very first steps of nucleation and growth of Ag on Pd(100) with thermal energy atom scattering. This technique is a very sensitive and nonperturbing probe to surface point defects, which permits an in situ and in-time monito ...
Superconducting YBCO thin films have been grown in-situ by three ion beam co-deposition sputtering. Both metal and oxide targets of Cu and Y and BaF2 and BaCO3 targets have been investigated. Film composition was determined by RBS and AES analysis. Films g ...
Expts. are described on the pyrolytic and photolytic laser chem. vapor deposition (LCVD) of Ga and GaAs, as well as hybrid deposition of the latter. Pyrolytic Ga deposits change in shape with laser power variations. A deposit in the shape of an annulus of ...
It is now generally recognized that the excitation frequency is an important parameter in radio-frequency (rf) plasma-assisted deposition. Very-high-frequency (VHF) silane plasmas (50-100 MHz) have been shown to produce high quality amorphous silicon films ...
Variable-temperature scanning tunneling microscopy was used to study the effect of kinetic cluster energy and rare-gas buffer layers on the deposition process of size-selected silver nanoclusters on a platinum(111) surface. Clusters with impact energies of ...
