We present ultra low-cycle fatigue experiments of axisymmetric nano-crystalline gold films of nano-thickness deformed by a spherical indenter using a recently developed freestanding membrane test. Freestanding membranes of gold were centrally deflected using a spherical indenter attached to a MEMS load cell. Fabrication of the films for these experiments yielded films 100 nm thick and 500 μm in...

VACUUM PUMPING STUDY OF TITANIUM-ZIRCONIUM-VANADIUM THIN FILMS* Yulin Li and Simon Ho, LEPP, Cornell University, Ithaca, NY 14853, USA Abstract Vacuum pumping via non-evaporable getter (NEG) thin film deposited directly onto the interior of a vacuum chamber is a novel way to achieve extreme high vacuum. As part of R&D efforts for the proposed Energy Recovery Linac at Cornell, the pumping perfor...

Dense SrZr0.95Y0.05O3 a and SrCe0.95Yb0.05O3 a thin films with perovskite structure were prepared on porous SrZr0.95Y0.05O3 a substrates by spin coating colloidal suspensions of powders prepared by combustion methods. Porous substrates were prepared by treating carbon/SrZr0.95Y0.05O3 a composites in air at 1273–1573 K in order to combust the carbon and partially sinter the resulting porous oxid...

A miniaturized arrangement based on magnetostrictive delay line (MDL) mechanism, able to be used as sensor, is realized using thin films technology. In order to obtain high-performance miniaturized magnetostrictive delay line arrangement we used Fe, Ni and Fe70B20Si6C4 amorphous thin films as magnetostrictive sensing element because of their better magnetic and magnetoelastic characteristics th...

This paper reports on molecular-based magnetic thin films of Prussian blue analogues (PBA) with high critical temperatures composed of mixed-valence chromium cyanides. The thin films of PBA were synthesized by means of electrodeposition technique. Morphology and magnetic study are presented in a function of electrochemical deposition conditions. We present the electrochemical methods as a promi...

The assistance of thin film deposition with low-energy ion bombardment influences their final properties significantly. Especially, the application of so-called hyperthermal ions (energy <100 eV) is capable to modify the characteristics of the growing film without generating a large number of irradiation induced defects. The nitrogen ion beam assisted molecular beam epitaxy (ion energy <25 eV) ...

Thermally stable nanoporous organosilicate thin films were realized by the microphase separation of pore-generating polymers mixed with an organosilicate matrix to be antireflective coatings (ARCs), for which a thin film with a refractive index (n) of 1.23 for zero reflection is required. The refractive index of such nanoporous organosilicate films can be tuned from 1.39 down to 1.23 by incorpo...

A low-energy hydrogen bombardment method, without using any chemical additives, has been designed for fine tuning both physical and chemical properties of molecular thin films through selectively cleaving C-H bonds and keeping other bonds intact. In the hydrogen bombardment process, carbon radicals are generated during collisions between C-H bonds and hydrogen molecules carrying ∼10 eV kinetic ...
