Thermal conductivity of hard carbon prepared from C 60 fulleren

We report measurements of thermal conductivity in 30–350 K range of hard fullerene-based carbon. The material has been prepared from C 60 fullerene under pressure and has an unusual combination of large hardness and relatively high electrical conductivity. Its thermal conductivity is about 5.5 W/mk...

Summary:We report measurements of thermal conductivity in 30–350 K range of hard fullerene-based carbon. The material has been prepared from C 60 fullerene under pressure and has an unusual combination of large hardness and relatively high electrical conductivity. Its thermal conductivity is about 5.5 W/mk at room temperature and decreases almost linearly in the investigated temperature range. The data obtained bear resemblance to the thermal properties of amorphous materials. It is consistent with the structural investigation that allows one to suggest the existence of short-range crystalline order in this transformed substance.
