The data suggest that the C60 chains provide additional conductive paths for charge carriers, increase the rate of phonon scattering, and block interior sites from sorbing other gas molecules 关键词: carbon nanotubes;electrical resistivity;fullerenes;phonon drag;Seebeck effect;thermal conductivity;thermoelectric power;C60-filled single-wall carbon nanotubes;electrical properties;thermal properties;electrical resistivity;thermopower;thermal conductivity;C60 chains;charge carrier conductive paths;phonon scattering rate;interior sites;gas molecule sorption;Seebeck coefficient;temperature dependence;phonon drag contribution;four-point resistivity;1.5 to 300 K;C60-C
