Abstract

A knowledge of interfacial mechanical properties is of considerable importance to the areas of oxidation, corrosion, metallization, and composite materials. We have developed an experimental apparatus capable of simultaneous measurements of elastic and anelastic properties of materials in controlled atmospheres (10 W to 10U Pa) from 25 to 1000C. The apparatus employs the technique of dynamic resonance in which a material's mechanical resonance spectrum can be determined over a range 10S to 10V Hz with resolution +-0.001 Hz. This resolution has enabled us to determine the mechanical properties of films as thin as approximately 10 nm. We present resonance results for thin films (approx.100 nm) of nickel and gold on sapphire substrates. Results suggest that nickel films on sapphire are adherent, i.e., cyclic strain is continuous at the film-substrate interface, over a range of temperature about the film growth temperature; whereas gold films show nonadherent behavior at all temperatures studied.

Modified pull test for the testing of very adherent films. [Zr on Sapphire substrate]

Conference Pawel, J; McHargue, C

The effectiveness of a thin film on a substrate depends largely on the degree of adhesion of the film to its substrate. Much effort has been put into developing reproducible, quantitative adhesion tests. The pull test is a direct measure of the tensile force required to remove the test film normal to the substrate surface. A technique was developed to introduce a reproducible flaw at the film/substrate interface in an attempt to lower the apparent adhesion of the film to within the range of the pull tester. This technique also promotes film failure at the artificial flaw and subsequent crackmore »« less
Effects of adhesion on the measurement of thin film mechanical properties by nanoindentation

Conference Tsui, T; Ross, C; Pharr, G

Experiments have been performed on soft aluminum films deposited on hard ceramic substrates to explore the influences of interfacial adhesion on mechanical property measurement by nanoindentation. The substrate materials included soda-lime silicate glass, aluminum oxynitride (ALON), and (100) sapphire. Thin films of high purity aluminum were sputtered onto each substrate to a thickness of 500 nm. Because the films were deposited simultaneously, the only major difference in the specimens was the nature of the substrate, which exerts an important influence on film adhesion through interfacial chemistry. Of the substrates examined, aluminum adheres strongly to glass and sapphire, but poorly tomore »« less

SISGR: Atom chip microscopy: A novel probe for strongly correlated materials

Technical Report Lev, Benjamin

Microscopy techniques co-opted from nonlinear optics and high energy physics have complemented solid-state probes in elucidating the order manifest in condensed matter materials. Up until now, however, no attempts have been made to use modern techniques of ultracold atomic physics to directly explore properties of strongly correlated or topologically protected materials. Our current program is focused on introducing a novel magnetic field microscopy technique into the toolbox of imaging probes. Our prior DOE ESPM program funded the development of a novel instrument using a dilute gas Bose-Einstein condensate (BEC) as a scanning probe capable of measuring tiny magnetic (and electric)more »« less
Superconducting electronic-film structures. Semiannual report, 1 January-30 June 1988

Technical Report Braginski, A; Gavaler, J; Talvacchio, J

Modification in Y-Ba-Cu-O growth procedures were instituted to eliminate non-superconducting near-surface layers observed in films. These include much higher ramp rates to the 850 C crystallization temperature of the as-deposited amorphous films and the use of an entirely in-situ processing. Films have now been grown that are superconducting up to the surface. Other Y-Ba-Cu-O films have been sputtered which are crystalline (tetragonal) as-deposited. These films. Gold layers deposited at room temperature on recent films were found to have contact resistance less than the limit of the apparatus sensitivity. Evidence for crystallinity and epitaxy was found in 10 nm YBCO filmsmore »« less
Surface Impedance of Superconducting Radio Frequency (SRF) Materials

Thesis/Dissertation Xiao, Binping

Superconducting radio frequency (SRF) technology is widely adopted in particle accelerators. There remain many open questions, however, in developing a systematic understanding of the fundamental behavior of SRF materials, including niobium treated in different ways and various other bulk/thin film materials that are fabricated with different methods under assorted conditions. A facility that can measure the SRF properties of small samples in a range of 2-40 K temperature is needed in order to fully answer these questions. The Jefferson Lab surface impedance characterization (SIC) system has been designed to attempt to meet this requirement. It consists of a sapphire-loaded cylindricalmore »« less
