Název v původním jazyce

Conductive tracks in graphene oxide foils induced by micro beams of MeV helium ions

Popis výsledku v původním jazyce

Conductive tracks based on reduced graphene oxide (rGO) were induced by MeV energy helium ion microbeams in graphene oxide (GO) sheets. The computerized X-Y step motors movement of the GO foil in front of the fixed ion microbeam in a high vacuum produces a reduction of the functionalized oxygen groups, generating a graphene-like track with high electrical conductivity. The conductive track generated on the insulating matrix has a depth dependent on the range of ions used, maintains the electrical properties even under bending stress, and can electrically connect devices made of the same carbon-based material or different materials. Scanning electron microscopy, characteristic X-ray emission, electron conductivity measurements, Raman spectroscopy, surface wetting and roughness, X-ray diffraction, and optical spectroscopy are employed to investigate the ion beam modifications induced in the GO structure.
