Atomic Hole Doping of Graphene

The application of graphene in nanoscale electronic devices requires the deliberate control of the density and character of its charge carriers. We show by angle-resolved photoemission spectroscopy that substantial hole doping in the conical band structure ...

Spatial modulation of the Dirac gap in epitaxial graphene

Klaus Kern

We use scanning tunneling spectroscopy (STS) at low temperatures to investigate the local electronic structure of mono- and bilayer graphene grown epitaxially on SiC(0001). Already for monolayer graphene, a gap opening is observed in the pi-bands at the Di ...

Similarity solutions for solute transport in fractal porous media using a time-and scale-dependent dispersivity

David Andrew Barry, Fang Liu

A specific form of the Fokker–Planck equation with a time- and scale-dependent dispersivity is presented for modelling solute transport in saturated heterogeneous porous media. By taking a dispersivity in the form of separable power-law dependence on both ...
