Scalable production of large quantities of defectfree few. An efficient maskless production of patterns in insulating foils of graphene oxide was carried out under impact of 5 mev alpha particle beams delivered by the ion micro beam system at the tandetron laboratory of the nuclear physics institute in rez czech republic. Graphene is the only allotrope of carbon in which every carbon atom is tightly bonded to its neighbours by an unique electronic cloud that raises several exceptional questions to quantum physics 3,5. Highly efficient hot electron harvesting from graphene. Graphene is the strongest, thinnest material known to exist. Methods to achieve largescale production of defect free graphene are needed to enable the commercial development of graphene based devices. It is the basic structural element of other allotropes, including graphite, charcoal, carbon nanotubes and fullerenes. Here, we proposed and demonstrated the possibility of efficiently extracting hot. Fundamental quantities and units for ionizing radiation revised report committee s.
