Discontinuous character of the ultrafast exciton Mott transition in monolayer WS
Subhadra Mohapatra, Samuel Palato, Nicholas Olsen +2
There are conflicting predictions and reports on the character of the exciton Mott transition (EMT) in monolayer transition metal dichalcogenides. It could be either a discontinuou…
Right On Time: Ultrafast Charge Separation Before Hybrid Exciton Formation
Lukas Gierster, Olga Turkina, Jan-Christoph Deinert +6
Organic/inorganic hybrid systems offer great potential for novel solar cell design combining the tunability of organic chromophore absorption properties with high charge carrier mo…
reduction at a DMSO/Cu(111) model battery interface
Angelika Demling, Sarah B. King, Philip Shushkov +1
In order to develop a better understanding of electrochemical reduction in non-aqueous solvents, we apply two-photon photoelectron spectroscopy to probe the dynamics…
Ultrafast generation and decay of a surface metal
Lukas Gierster, Sesha Vempati, Julia Stähler
Band bending at semiconductor surfaces induced by chemical doping or electric fields can create metallic surfaces with properties not found in the bulk, such as high electron mobil…
Local Aspects of Hydrogen-Induced Metallization of the ZnO(100) Surface
J. -C. Deinert, O. T. Hofmann, M. Meyer +2
This study combines surface-sensitive photoemission experiments with density functional theory (DFT) to give a microscopic description of H adsorption-induced modifications of the…
Localization-dependent charge separation efficiency at an organic/inorganic hybrid interface
Laura Foglia, Lea Bogner, Martin Wolf +1
By combining complementary optical techniques, photoluminescence and time-resolved excited state absorption, we achieve a comprehensive picture of the relaxation processes in the o…
Ultrafast exciton formation at the ZnO(100) surface
J. -C. Deinert, D. Wegkamp, M. Meyer +3
We study the ultrafast quasiparticle dynamics in and below the ZnO conduction band using femtosecond time-resolved two-photon photoelectron spectroscopy. Above band gap excitation…
