Tuning Ultra-Narrow Direct Bandgap in alpha-Sn Nanocrystals: A CMOS-Compatible Approach for THz Applications
Tiziano Bertoli, Elena Stellino, Francesco Minati +14
alpha-Sn has recently been attracting significant interest due to its unique electronic properties. However, this allotrope of Sn is stable only below 13 °C and alternative options…
Fine-Tuning of the Excitonic Response in Monolayer WS2 Domes via Coupled Pressure and Strain Variation
Elena Stellino, Beatrice D'Alò, Elena Blundo +2
We present a spectroscopic investigation into the vibrational and optoelectronic properties of WS2 domes in the 0-0.65 GPa range. The pressure evolution of the system morphology, d…
Experimental investigation of electronic interactions in collapsed and uncollapsed LaFe2As2 phases
Ilaria Pallecchi, Elena Stellino, Paolo Postorino +4
The iron-based pnictide LaFe2As2 is not superconducting as-synthesized, but it becomes such below Tc around 12 K upon annealing, as a consequence of a structural transition from a…
Far-Infrared Signatures for a Two-Steps Pressure-Driven Metallization in Transition Metal Dichalcogenides
Elena Stellino, Beatrice D'Alo', Francesco Capitani +6
We present a high-pressure investigation of the semiconductor-to-metal transition in MoS2 and WS2 carried out by synchrotron-based far-infrared spectroscopy, to reconcile the contr…
Raman Scattering with infrared excitation resonant with MoSe indirect band gap
Simone Sotgiu, Tommaso Venanzi, Francesco Macheda +4
Resonance Raman scattering, which probes electrons, phonons and their interplay in crystals, is extensively used in two-dimensional materials. Here we investigate Raman modes in Mo…
Polarization analysis of first- and second-order Raman scattering from MoTe single crystal
S. Caramazza, A. Collina, E. Stellino +2
We report on Raman experiments performed on a single crystal MoTe sample. The system belongs to the wide family of Transition Metal Dichalcogenides which includes several of th…
