Figure 2: Thermal conductivity measurements ... measurement and measuring the block temperature. Thermal resistance was computed as the temperature difference between the resistor and thermocouple ...

If we divide 1 m2 of our envelope by the temperature difference between its faces ... obeys the thickness of each layer and its thermal conductivity (ability to conduct the heat of each material).

They recorded the thermal conductivity (k) of graphite (8.5 µm thickness) to be 4300 Watts per meter-kelvin under room temperature. The value was well above that recorded for diamond and slightly ...
