Thin films with ultra-low thermal expansion.

Ultra-low coefficient of thermal expansion (CTE) is an elusive property, and narrow temperature ranges of operation and poor mechanical properties limit the use of conventional materials with low CTE. We structured a periodic micro-array of bi-metallic cells to demonstrate ultra-low effective CTE with a wide temperature range. These engineered tunable CTE thin film can be applied to minimize th...

The Frictional Behavior of Thin Halide Films on Iron

The frictional properties of thin inorganic halide films on iron measured in ultrahigh vacuum

Friction coefficients are measured in ultrahigh vacuum using a tungsten carbide tribopin against thin films of sodium chloride and potassium iodide deposited onto clean iron. It is found, in accordance with previous measurements for potassium chloride on iron, that the friction coefficient falls from an initial value of 2 for the clean iron surface to a minimum value after a few tens of Ångstro...

The direct growth of gold rods on graphene thin films.

Long gold rods were directly grown on a reduced graphene oxide (RGO) surface by seed-mediated and seedless approaches for the fabrication of a novel Raman scattering platform. The Raman scattering signal from RGO was significantly enhanced by 34-fold at the tip of the grown gold rod.
