Time dependence of the excited-state signal in 2D TaS2 and spectral function simulations. The snapshots of the signal compose an "ultrafast movie" of the band structure

During his PhD studies, Federico Andreatta discovered and characterized the structure of tantalum-based materials that are only one-atom-thick. When matter is confined to such a low dimension, intriguing electronic properties arise. These were probed by Federico Andreatta for the first time on two-dimensional tantalum disulfide by means of a state-of-the-art technique that generates an ultrafast “movie” of the electrons in the energy- and momentum-space after being perturbed by an intense laser pulse. Such and related new research findings represent a first step toward the comprehension of quantum confinement and the implementation of quantum technologies for the production of clean energy.

The PhD study was completed at the Department of Physics and Astronomy, Faculty of Natural Sciences, Aarhus University.

This summary was prepared by the PhD student.
