This chapter reviews three new experimental techniques for the study andcharacterization of carbon nanotubes and the exploration of novel phenomena. First,imaging and spectroscopy on the nanoscale is presented using near-field opticalmicroscopy. Secondly, phonon spectroscopy with atomic resolution is demonstratedbased on inelastic electron tunneling. Finally, coherent phonon generation byultrashort...
MIIPS is a popular method for compressing femtosecond pulses. It is not ideal for complex pulses, like those produced by self-phase modulation. We show that several limitations are fixed by an improvement called G-MIIPS.
Coherent control in plasmonic nanostructures is a door to space-time confinement of optical excitation and femtosecond super-resolution spectroscopy. Towards this goal, here we demonstrate femtosecond pulse-shaping of single gold nanostructure and local phase compensation.
Graphene is in the focus of research due to its unique electronic and optical properties. Intrinsic graphene is a zero gap semiconductor with a linear dispersion relation for E-k leading to zero-effective-mass electrons and holes described by Fermi-Dirac theory. Since pristine graphene has no bandgap no photoluminescence would be expected. However, recently several groups showed non-linear photoluminescence...
