Abstract:Grafen är ett effektivt tvådimensionellt material som består av kolatomer arrangerade i ett hexagonalt gitter. Tack vare speciella elektroniska egenskaper, som laddningsbärarnas höga mobilitet, anses grafen vara en lovande kandidat för framtida elektroniska tillämpningar. Fristående grafen upptäktes så sent som 2004, men sedan dess har materialet blivit fokus för otaliga studier. Förutom ett vetenskapligt intresse, har grafen under den senaste tiden också skapat ett betydande kommersiellt intresse. |
