Graphite, a crystalline shape of carbon, has a special layered structure that permits superb heat switch, making it a useful ...
It melts at 3727 C. The stable form of carbon at room temperature is Graphite which has a hexagonal crystal structure. (Top diagram) Diamond is metastable at room temperature and has a diamond cubic ...
Huang and collaborators have exploited this effect to realize thermal rectification in graphite. They fabricated structures ...
The trick is to absorb the light in the bulk of the structure and not within the uppermost layers, as happens in natural graphite, and provides another beautiful example of how structuring a ...
