The empty states of graphene and graphene adsorbed on nickel (1 1 1) are studied using a plane-wave pseudo-potential method based on local density functional theory. The analysis is used to assign spectroscopic features observed in secondary electron

Multiwalled carbon nanotubes (MWCNT) have been synthesized on graphite cathodes by arc discharge in He atmosphere, either by using a catalytic Ni–Cr mixture or without catalysts. A preliminary scanning electron microscopy (SEM) investigation eviden

Multiwalled carbon nanotubes have been deposited on graphite cathodes by using an arc discharge technique in He atmosphere, with the insertion of a catalytic Ni-Cr mixture as well as without catalysers. The topography of such deposition has been inve

Publikováno v: Surface Science. 601:2828-2831

We present a comparative study of the electronic properties of sodium and lithium intercalated single walled carbon nanotubes in a bucky paper sample by electron energy loss spectroscopy and photoemission spectroscopy. We have found that at room temp

The co-adsorption of oxygen and carbon monoxide on the Ni(1 1 1) surface was investigated by high resolution electron energy loss spectroscopy. We found that CO molecules adsorbed at 150 K on the oxygen pre-covered surface have two distinct internal
