Abstract
The subject of this study is the thermoelectric efficiency (Z) and the thermoelectric parameter (ZT) of carbon nanocomposites, namely, the structures consisting of graphite-like (gr) and diamond-like (d) regions made of sp2 and sp3 hybridized carbon atoms, respectively. The impact of heat transfer across the boundary between sp2 and sp3 areas is analyzed for the first time. It is shown that the interfacial thermal resistance (Kapitza resistance) is not lower than the thermal resistance in the macroscopic gr region. The influence of various factors on the Kapitza resistance is analyzed. The value of ZT ≈ 3.5 at room temperature, taking into account the interfacial thermal resistance, is significantly higher than it would be in gr films (ZT ≈ 0.75).
