Research Abstract |
Physical properties of Mix-material deposition layers were analyzed by using transmission electron microscopy. Deposition layers were composed by amorphous like carbon and metal layers. The metal layers mainly including Fe seem to act as the initiator of the exfoliation of the deposition layers. In addition, retention rate of hydrogen isotopes in deposition layer was higher than that of the bulk carbon materials.
