Single photon emitters in thin GaAsN nanowire tubes grown on Si
Nadine Denis, Didem Dede, Timur Nurmamytov +8
III-V nanowire heterostructures can act as sources of single and entangled photons and are enabling technologies for on-chip applications in future quantum photonic devices. The un…
Low charge-noise nitrogen-vacancy centers in diamond created using laser writing with a solid-immersion lens
Viktoria Yurgens, Josh A. Zuber, Sigurd Flågan +6
We report on pulsed-laser induced generation of nitrogen-vacancy (NV) centers in diamond facilitated by a solid-immersion lens (SIL). The SIL enables laser writing at energies as l…
Probing Lattice Dynamics and Electronic Resonances in Hexagonal Ge and SixGe1-x Alloys in Nanowires by Raman Spectroscopy
Diego de Matteis, Marta De Luca, Elham M. T. Fadaly +5
Recent advances in nanowire synthesis have enabled the realization of crystal phases that in bulk are attainable only under extreme conditions, i.e. high temperature and/or high pr…
Experimental demonstration of the suppression of optical phonon splitting in 2D materials by Raman spectroscopy
Marta De Luca, Xavier Cartoixà, David I. Indolese +7
Raman spectroscopy is one of the most extended experimental techniques to investigate thin-layered 2D materials. For a complete understanding and modeling of the Raman spectrum of…
A Universal Length-Dependent Vibrational Mode in Graphene Nanoribbons
Jan Overbeck, Gabriela Borin Barin, Colin Daniels +13
Graphene nanoribbons (GNRs) have attracted considerable interest as their atomically tunable structure makes them promising candidates for future electronic devices. However, obtai…
New insights in the lattice dynamics of monolayers, bilayers, and trilayers of WSe2 and unambiguous determination of few-layer-flakes' thickness
Marta De Luca, Xavier Cartoixà, Javier Martín-Sánchez +4
Among the most common few-layers transition metal dichalcogenides (TMDs), WSe2 is the most challenging material from the lattice dynamics point of view. Indeed, for a long time the…
Unusual spin properties of InP wurtzite nanowires revealed by Zeeman splitting spectroscopy
D. Tedeschi, M. De Luca, P. E. Faria Junior +8
In this study, we present a complete experimental and theoretical investigation of the fundamental exciton Zeeman splitting in wurtzite InP nanowires. We determined the exciton gyr…
Common nonlinear features and spin-orbit coupling effects in the Zeeman splitting of novel wurtzite materials
Paulo E. Faria Junior, Davide Tedeschi, Marta De Luca +3
The response of semiconductor materials to external magnetic fields is a reliable approach to probe intrinsic electronic and spin-dependent properties. In this study, we investigat…
Effects of Dielectric Stoichiometry on the Photoluminescence Properties of Encapsulated WSe2 Monolayers
Javier Martín-Sánchez, Antonio Mariscal, Marta De Luca +8
Two-dimensional transition-metal-dichalcogenide semiconductors have emerged as promising candidates for optoelectronic devices with unprecedented properties and ultra-compact perfo…
