Abstract Scope |
Ion beam modification is well known to tailor the electrical properties of materials; however, the potential of the technique to alter the thermal, mechanical, and acoustic properties of thin films and coatings is often overlooked. By careful selection of the ion species, energy, and dose, the thermal conductivity and thermal boundary conductance of an interface can be controlled. In a similar manner, the mechanical and acoustic properties of the surface and subsurface can be modified. This presentation will highlight recent advancements in ion beam modification as well as some in-situ characterization tools that permit rapid characterization of the thermal, mechanical, and acoustic properties of sub-surfaces, as they are being tailored.
