The tuning of carrier concentrations in graphene is at the heart of graphenebased nanoelectronic and optoelectronic applications. Molecular doping, that is, taking charges from the adsorbed molecules, shows promise as a means by which to change carri

The position and width of the Raman G-line was analyzed for unintentionally doped single-layered graphene samples. Results indicate a significant heating of the monolayer by the laser beam. Moreover, a weak additional component was resolved in the G-

The hollow core inside a carbon nanotube1 can be used to confine single molecules2, 3 and it is now possible to image the movement of such molecules inside nanotubes4, 5. To date, however, it has not been possible to control this motion, nor to detec

Single-walled carbon nanotubes (SWNTs) produced by the arc-discharge method using non-magnetic catalysts were filled with Dy@C 82 endohedral metallofullerenes. Transport measurements were performed on (Dy@C 82 )@SWNT metallofullerene peapod samples i

A technique is presented which allows one to combine TEM investigations with transport measurements and potentially a wide range of other investigations on the same nanoobject. Using this technique, we have obtained high-resolution transmission elect

It is known that monolayer graphene has an extraordinarily high intrinsic mobility of the charge carriers. An important complication is the presence of strong mesoscopic resistance fluctuations (MRFs) that, in graphene, persist to relatively high tem

Being one of the main methods for studying the atomic structure of carbon materials, high resolution TEM suffers from a serious flaw as the energy of electrons, necessary to obtain atomic resolution (200–300 keV), is far above the kick-off damage t
