GaAs/GaP Superlattice Nanowires for Tailoring Phononic Properties at the Nanoscale: Implications for Thermal Engineering
Aswathi K. Sivan, Begoña Abad, Tommaso Albrigi +8
The possibility to tune the functional properties of nanomaterials is key to their technological applications. Superlattices, i.e., periodic repetitions of two or more materials in…
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…
Photoluminescence of MAPbI: a semiconductor science and technology point of view
Valerio Campanari, Antonio Agresti, Sara Pescetelli +6
In this work, we perform steady-state continuous wave (cw) photoluminescence (PL) measurements on a MAPbI thin film in the temperature range of 10-160 K, using excitation densi…
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…
