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…

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…
