Defect Induced Photoluminescence from Dark Excitonic States in Individual Single-Walled Carbon Nanotubes
Hayk Harutyunyan, Tobias Gokus, Alexander A. Green +3
We show that new low-energy photoluminescence (PL) bands can be created in semiconducting single-walled carbon nanotubes by intense pulsed excitation. The new bands are attributed…
Raman Spectroscopy of Graphene Edges
C. Casiraghi, A. Hartschuh, H. Qian +5
Graphene edges are of particular interest, since their chirality determines the electronic properties. Here we present a detailed Raman investigation of graphene flakes with well d…
Rayleigh Imaging of Graphene and Graphene Layers
C. Casiraghi, A. Hartschuh, E. Lidorikis +5
We investigate graphene and graphene layers on different substrates by monochromatic and white-light confocal Rayleigh scattering microscopy. The image contrast depends sensitively…
