Thermometric Calibration of the Ultrafast Relaxation Dynamics in Plasmonic Au Nanoparticles
Marzia Ferrera, Giuseppe Della Valle, Maria Sygletou +8
The excitation of plasmonic nanoparticles by ultrashort laser pulses sets in motion a complex ultrafast relaxation process involving the gradual re-equilibration of the system's el…
Sharp spectral variations of the ultrafast transient light extinction by bimetallic nanoparticles in the near-UV
Tadele Otomalo, Lorenzo Di Mario, Cyrille Hamon +6
Noble metal nanoparticles exhibit localized plasmon resonance modes that span the visible and near-infrared spectral ranges and have many applications. Modifying the size, shape, a…
Diameter dependence of the temperature dynamics of hot carriers in photoexcited GaAsP nanowires
Aswathi K Sivan, Lorenzo Di Mario, Yunyan Zhang +6
Nanowires (NWs) with their quasi-one-dimensionality often present different structural and opto-electronic properties than their thin-film counterparts. The thinner they are the la…
Ultrafast optical spectroscopy of semiconducting and plasmonic nanostructures and their hybrids
Daniele Catone, Lorenzo Di Mario, Faustino Martelli +7
The knowledge of the carrier dynamics in nanostructures is of fundamental importance for the development of (opto)electronic devices. This is true for semiconducting nanostructures…
Plasmon induced resonant effects on the optical properties of Ag-decorated ZnSe nanowires
Aswathi K Sivan, Lorenzo Di Mario, Daniele Catone +4
In this work we present how the optical properties of ZnSe nanowires are modified by the presence of Ag nanoparticles on the sidewalls of the ZnSe nanowires. In particular we show…
Ultrafast relaxation of photoexcited superfluid He nanodroplets
M. Mudrich, A. LaForge, F. Stienkemeier +21
The relaxation of photoexcited nanosystems is a fundamental process of light-matter interaction. Depending on the couplings of the internal degrees of freedom, relaxation can be ul…
Carrier dynamics in silicon nanowires studied via femtosecond transient optical spectroscopy from 1.1 to 3.5 eV
Lin Tian, Lorenzo Di Mario, Aswathi K Sivan +5
We present femtosecond transient transmission (or absorbance) measurements in silicon nanowires in the energy range 1.1-3.5 eV, from below the indirect band-gap to above the direct…
Autoionization dynamics of He nanodroplets resonantly excited by intense XUV laser pulses
Y. Ovcharenko, A. LaForge, B. Langbehn +16
The ionization dynamics of helium droplets in a wide size range from 220 to 10^6 He atoms irradiated with intense femtosecond extreme ultraviolet (XUV) pulses of 10^9 ÷ 10^{12} W/c…
Enhanced ionization of embedded clusters by Electron Transfer Mediated Decay in helium nanodroplets
A. C. LaForge, V. Stumpf, K. Gokhberg +13
Here, we report the observation of electron transfer mediated decay (ETMD) involving Mg clusters embedded in helium nanodroplets which is initiated by the ionization of helium foll…
EUV ionization of pure He nanodroplets: Mass-correlated photoelectron imaging, Penning ionization and electron energy-loss spectra
D. Buchta, S. R. Krishnan, N. B. Brauer +11
The ionization dynamics of pure He nanodroplets irradiated by EUV radiation is studied using Velocity-Map Imaging PhotoElectron-PhotoIon COincidence (VMI-PEPICO) spectroscopy. We p…
Penning ionization of doped helium nanodroplets following EUV excitation
D. Buchta, S. R. Krishnan, N. B. Brauer +11
Helium nanodroplets are widely used as a cold, weakly interacting matrix for spectroscopy of embedded species. In this work we excite or ionize doped He droplets using synchrotron…
