The authors have reported that dielectric breakdown strength improves by 34 % by uniformly dispersing 0.6 wt% fullerene in epoxy resin. In this paper, quantum chemistry calculations are performed on HTR / fullerene (C60) composites to estimate the electron trap depth from the electronic state density. As a result, it is found that the electron trap depth of the epoxy/fullerene composite and HTR/C60 are calculated as 3.0 and 3.7 eV, respectively. The increase in the electron trap depth suggests that the addition of fullerene to HTR can suppress acceleration of high energy electron leading to increase in the dielectric breakdown strength.
