The electronic density of states (DOS) in carbon nanotubes (CNTs) was recently measured using a structure comprising a single CNT-based field effect transistor (FET) device with an indium (In) electrode. Here, we report the bonding characteristics and electronic structure of the contact interface between Group 13 metals (In, Ga, Al) and (8,0) semiconducting CNTs using first-principles density functional...
To investigate the microscopic mechanism for the wet-chemical hydrogenation of graphene, first principles density functional calculations were performed for the hydrogen transfer reaction between the graphene surface and a mixture of hydrogen carrier and electron donor. For the hydrogen transfer from CH3OH to graphene, as commonly used in Birch-type reductions, the presence of alkali atoms is important...
Nitrogen-doped graphene–silver nanoparticle hybrids were prepared by thermal treatment of graphite oxide (GO) with glycine and silver nitrate at 500°C. Glycine was used to reduce the nitrate ions, resulting in the decomposition of a glycine–nitrate mixture near 200°C. The products of decomposition act as sources for nitrogen doping. The thermal treatment of a mixture of GO, glycine and silver nitrate...
