Is There a Market for New Heat Sink Materials with Low CTE?

This is an excerpt from "Heat Sink Materials" by Ken Gilleo, PhD

Heat sinks have been used before the dawn of solid-state electronics and the industry is well established on a global basis including plants in China. Aluminum is the de facto standard material even though it is far from ideal. Copper has better thermal conductivity and is gaining share as smaller, more efficient heat sinks and related products are required. Copper alloys and constructions using copper are also being used today. It should be noted that low CTE alloys are already in use and a new material must be compared to these products. Non-metals are also likely to appear soon as nanotechnology attacks thermal management problems.
