Very high thermal conductivity measurements up to 22,600 w m −1 K −1 were reported by Fenton, E.W., Rogers, J.S. and Woods, S.D. in reference 570 on page 1458, 41, 2026–33, 1963. The data is listed on pages 6 through 8 and graphed on page 1 where Fenton and company are on curves 63 and 64.
However, for dimensions below 7 to 10 nm nodes, the decreased volume of available conducting metal will force innovative material and integration approaches towards novel interconnect architectures. Also for power and high-performance applications the most critical challenges are high ampacity, thermal conductivity and electromigration resistance.
For example, carbon fibers are commonly used in aluminium matrix to synthesize composites showing low density and high strength. However, carbon reacts with aluminium to generate a brittle and water-soluble compound Al 4 C 3 on the surface of the fiber. To prevent this reaction, the carbon fibers are coated with nickel or titanium boride.
A carbon nanotube (CNT) is a tube made of carbon with a diameter in the nanometre range . They are one of the allotropes of carbon. Two broad classes of carbon nanotubes are recognized: Single-walled carbon nanotubes (SWCNTs) have diameters around 0.5–2.0 nanometres, about 100,000 times smaller than the width of a human hair.
Huang et al. demonstrated a thermally conductive composite shows an enhancement of 0.65W/m/K with a 0.3wt% loading of VANTA, whereas the enhanced thermal conductivity of a composite with of 0.3 wt% loading of randomly dispersed CNT is below 0.05W/m/K. Tong et al. reported that CNT arrays can be used effectively as thermal interface materials ...
