    Long lived photo excitations in (6, 5) carbon nanotubes

    We study the photo-induced transmission change (ΔT/T) upon quasi-continuum laser excitation, for different modulation frequency and excitation intensity in films of (6, 5) enriched CoMoCat single wall nanotube...

    Electronic structure and dynamics of optically excited single-wall carbon nanotubes

    We have studied the electronic structure and charge-carrier dynamics of individual single-wall carbon nanotubes (SWNTs) and nanotube ropes using optical and electron–spectroscopic techniques. The electronic st...

    Charge-carrier dynamics in single-wall carbon nanotube bundles: a time-domain study

    We present a real-time investigation of ultra-fast carrier dynamics in single-wall carbon nanotube bundles using femtosecond time-resolved photoelectron spectroscopy. The experiments allow us to study the proc...

    Time-Resolved Two-Color Photoelectron Spectroscopy at Bare and Adsorbate Covered Metal Surfaces

    We investigate the influence of rare-gas (Xe, Kr) overlayers on the ultra-fast dynamics of photoexcited electrons in image-potential states on Cu(111). A density matrix calculation using the Liouville-von-Neum...
