Strong nonlinear terahertz response induced by Dirac surface states in Bi2Se3 Topological Insulator
Flavio Giorgianni, Enrica Chiadroni, Andrea Rovere +17
Electrons with a linear energy/momentum dispersion are called massless Dirac electrons and represent the low-energy excitations in exotic materials like Graphene and Topological In…
Advancing Atmospheric Pollution Monitoring with Airborne THz Spectrometer
Candida Moffa, Alessandro Curcio, Camilla Merola +8
This study details the development and validation of an airborne THz spectrometer designed for real-time, remote detection of atmospheric pollutants. The platform couples a stabili…
Universal threshold for femtosecond laser ablation with oblique illumination
Xiao-Long Liu, Weibo Cheng, Massimo Petrarca +1
We quantify the dependence of the single-shot ablation threshold on the angle of incidence and polarization of a femtosecond laser beam, for three dissimilar solid-state materials:…
Deciphering hidden layers images through terahertz spectral fingerprints
Candida Moffa, Daniele Francescone, Alessandro Curcio +5
Terahertz radiation enables non destructive, depthresolved analysis of layered artworks. This study demonstrates THz multispectral imaging ability to reveal concealed text beneath…
Terahertz prototype for air pollutants detection
Candida Moffa, Alessandro Curcio, Camilla Merola +11
In this work, we propose a prototype set-up exploiting terahertz time-domain spectroscopy (THz-TDS) to investigate gaseous compounds. The system is portable and allows to perform r…
