Note that Fourier’s law applies for all matter, regardless of its state (solid, liquid, or gas), therefore, it is also defined for liquids and gases. The heat transfer characteristics of a solid material are measured by a property called the thermal conductivity, k (or λ), measured in W/m.K. Silicon nanocrystals (SiNCs) are well known for their size-dependent optical and electronic properties; they also have the potential for low yet controllable thermal properties. In fact, in pure metals such as gold, silver, copper, and aluminum, the heat current associated with the flow of electrons by far exceeds a small contribution due to the flow of phonons. Accordingly, transport of thermal energy may be due to two effects: The unique feature of metals as far as their structure is concerned is the presence of charge carriers, specifically electrons. A thermal percolation is observed at 1.78 vol % SiC filler. Dense gases such as xenon and dichlorodifluoromethane have low thermal conductivity. m .
