Impact of electron solvation on ice structures at the molecular scale
Cord Bertram, Philipp Auburger, Michel Bockstedte +3
We determine the impact of electron solvation on DO structures adsorbed on Cu(111) with low temperature scanning tunneling microscopy, two-photon photoemission, and ab initio t…

Revealing the Competing Contributions of Charge Carriers, Excitons, and Defects to the Non-Equilibrium Optical Properties of ZnO
Laura Foglia, Sesha Vempati, Boubacar Tanda Bonkano +4
Due to its wide band gap and high carrier mobility, ZnO is an attractive material for light-harvesting and optoelectronic applications. Its functional efficiency, however, is stron…
