Strain-induced dynamic control over the population of quantum emitters in two-dimensional materials
Giuseppe Ronco, Abel Martínez-Suárez, Davide Tedeschi +11
The discovery of quantum emitters (QEs) in two-dimensional materials (2D) has triggered a surge of research to assess their suitability for quantum photonics. While their microscop…
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…
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…
Comparison of different bonding techniques for efficient strain transfer using piezoelectric actuators
Dorian Ziss, Javier Martín-Sánchez, Thomas Lettner +5
In this paper strain transfer efficiencies from single crystalline piezoelectric lead magnesium niobate-lead titanate (PMN-PT) substrate to a GaAs semiconductor membrane bonded on…
Reversible Control of In-plane Elastic Stress Tensor in Nanomembranes
Javier Martín-Sánchez, Rinaldo Trotta, Giovanni Piredda +10
Strain engineering allows the physical properties of materials and devices to be widely tailored, as paradigmatically demonstrated by strained transistors and semiconductor lasers…
Energy-tunable sources of entangled photons: a viable concept for solid-state-based quantum relays
Rinaldo Trotta, Javier Martín-Sánchez, Istvan Daruka +2
We propose a new method of generating triggered entangled photon pairs with wavelength on demand. The method uses a micro-structured semiconductor-piezoelectric device capable of d…
