| Description | Journal: Nanotechnology We present direct observation of the transformation of dense amorphous carbon cluster into diamond nanocrystalline under electron beam irradiation by in situ transmission electron microscopy, whereas the surrounding carbon matrix hardly changed. Our findings provide clear and convincing evidence for the diamond nanocrystalline evolving from energetic amorphous carbon sites. Furthermore, graphitization of amorphous carbons usually demands a high temperature combined with high pressure (HTHP). Hence, graphitization of amorphous carbons at relatively lower temperatures is highly desired. Here we offered a useful method for catalyst-free graphitization of amorphous carbons by employing moderate electron beam irradiation and without external heating was applied. |
