“…Gold films have also been used as electrodes in electrochemical studies and applications. 16 The gold film can be evaporated onto the quartz surface of a quartz crystal microbalance. A thin metallic layer (e.g., titanium or chromium) is often used to promote the adhesion of metallic layers to the underlying substrate.…”

In nanoindentation, the occurrence of cracks, pileup, sink-in, or film delamination adds additional complexity to the analysis of the load-displacement curves. Many techniques and analysis methods have been used to extract both qualitative and quantitative information from the indentation test both during and after the test. Much of this information is obtained indirectly or may even be overlooked by current testing methods (e.g., cracks that open only during the loading cycle of the test may go unnoticed from a typical residual indentation analysis). Here we report on the development of a miniature depth-sensing nanoindentation instrument and its integration into a high-resolution scanning electron microscope. Real-time observation of the nanoindentation test via scanning electron microscopy allows for visualization and detection of certain events such as crack initiation, pileup, or sink-in, and other material deformation phenomena. Initial results from aluminum 〈100〉 and a thin gold film (∼225 nm) are presented.

“…If one chain bends, another chain will bend on top of it, and packing of the terminal ends of the chains of the few surrounding molecules will be disordered relative to that of trans-extended chains. Molecules may kink due to, for example, the presence of grain boundaries or step edges in the metal film or impurities in solvents and reagents that deposit on the metal surface during SAM formation and cause irregularities in the metal lattice (Hieber 1976;Laibinis et al 1991b;Hoogvliet & van Bennekom 2001).…”

In this paper, we discuss the current state of organic and molecular-scale electronics, some experimental methods used to characterize charge transport through molecular junctions and some theoretical models (superexchange and barrier tunnelling models) used to explain experimental results. Junctions incorporating self-assembled monolayers of organic molecules-and, in particular, junctions with mercury-drop electrodes-are described in detail, as are the issues of irreproducibility associated with such junctions (due, in part, to defects at the metal-molecule interface).

“…That is, the transition may still exist but occur (as a sudden increase of the resistance) at a H 2 concentration which may be out of the upper limit of 2 % in the experiments by Kim et al [12]. Since Ti has been widely used to form a buffer (or adhesion) layer for metal films deposited on oxide substrates [13][14][15], further experiments on the effect of a Ti buffer layer on the phase transition in Pd/H system not only will be crucial for achieving H 2 sensors with a wide detection range but also can stimulate exploration on new phenomena in Ti-buffered metal systems.…”

Hydrogen responses of ultrathin Pd films and nanowire networks with a Ti buffer layer

We report on hydrogen responses of ultrathin films and nanowire networks of palladium on titanium buffered silicon substrates and filtration membranes, respectively. We found that in both systems signatures such as retarding responses and saturation of the resistance changes at high hydrogen concentrations associated with the transition from Pd/H solid solution to Pd hydride diminish with decreasing the thickness of the palladium layer from 7 to 2 nm. Our results not only reveal a new way to suppress the phase transition in Pd/H system but also provide an alternative approach to achieve fast and sensitive hydrogen sensors with a wide concentration detection range.
