Exciton Dynamics and Anisotropy in 2D Metal Organochalcogenolate Semiconductors by Lee, Woo Seok

“…Using time-resolved and temperature dependent optical spectroscopy, combined with sub-gap photoexcitation studies, we demonstrate that the exciton dynamics in AgSePh films are dominated by the interaction of free-excitons with extrinsic defect states, whereas the dynamics in AgTePh are dominated by intrinsic exciton selftrapping behavior. …”

Electronic structures of twisted two-dimensional materials studied by angle-resolved photoemission spectroscopy by Pei, D

“…Besides, we observed iconic topological surface states with chiral edge modes around the Γ point, forming long Fermi-arc winding across the Brillouin zone. Surprisingly, we found the anomalous polarization dependence of the observed arc states in PtGa, the origin of which could be rooted in the chiral crystal structure.…”

Surface engineering to manipulate solar energy for thermal management by Fei, Jipeng

“…Through matching the refractive index between porous membrane and filling liquids, Mie scattering along pore boundaries was successfully tuned, achieving the switch between solar transmissive and reflective modes. …”
