Metallic crossover through the tilt-free transition in LaNiO at high pressure and temperature
Bastien Michon, Yingpeng Yu, Beatrice D'Alò +8
LaNiO, a bilayer nickelate with Ruddlesden-Popper structure, undergoes a pressure-induced structural transition from a tilted Amam phase to an untilted Fmmm (or I4/mmm)…

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…

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…
