Electronic properties of mesoscopic graphene structures: Charge confinement and control of spin and charge transport

Abstract: This brief review discusses electronic properties of mesoscopic graphene-based structures. These allow controlling the confinement and transport of charge and spin; thus, they are of interest not only for fundamental research, but also for applications. The graphene-related topics covered here are: edges, nanoribbons, quantum dots, pn-junctions, pnp-structures, and quantum barriers and waveguides. This review is partly intended as a short introduction to graphene mesoscopics.

“…[1][2][3][4][5][6][7][8][9][10][11] When graphene is reduced to graphene nanostructures, new effects related to size-quantization and edges appear. [11][12][13] Considerable experimental effort has been made aiming at producing graphene nanostructures with desired shape and edges. [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32] Among graphene nanostructures, nanoribbons and quantum dots are of particular interest.…”

“…Graphene, a two-dimensional (2D) mono-atomic-thick sheet of sp 2 hybridized carbon, exhibits a unique combination of structural, mechanical, electronic, thermal, and possibly magnetic properties, and is viewed today as a very promising material for various applications in a vast range of nanotechnologies, see reviews [1][2][3][4][5]. However "graphene is not the end of the road" [6]; and numerous efforts have been focused recently on the search of graphene-based materials with novel functionalities, in particular, through adsorption of various atoms or molecules on the surface of grapheme [7,8].…”
