Published in 2024 at "Nano letters"

DOI: 10.1021/acs.nanolett.4c00949

Abstract: Topological Dirac nodal-line semimetals host topologically nontrivial electronic structure with nodal-line crossings around the Fermi level, which could affect the photocarrier dynamics and lead to novel relaxation mechanisms. Herein, by using time- and angle-resolved photoemission… read more here.
