Enhanced third harmonic response of the PtTe transition metal dichalcogenide
Leone Di Mauro Villari, Simone Grillo, Olivia Pulci +3
We investigate the third harmonic response of platinum ditelluride (PtTe), a Dirac semimetal belonging to the transition metal dichalcogenides class. Due to its topological pro…

Tunable second harmonic generation in 2D materials: comparison of different strategies
Simone Grillo, Elena Cannuccia, Maurizia Palummo +2
Nonlinear optical frequency conversion, where optical fields interact with a nonlinear medium to generate new frequencies, is a key phenomenon in modern photonic systems. However,…
