Journal ArticleDOI
Gold work function reduction by 2.2 eV with an air-stable molecular donor layer
Benjamin Bröker,Ralph-Peter Blum,Johannes Frisch,Antje Vollmer,Oliver T. Hofmann,Ralf Rieger,Klaus Müllen,Jürgen P. Rabe,Egbert Zojer,Norbert Koch +9 more
TL;DR: In this article, neutral methyl viologen (1,1′-dimethyl-1H,1,H-[4,4′]bipyridinylidene, MV0) was used for electron transfer on Au(111).
Journal ArticleDOI
Probing the energy levels in hole-doped molecular semiconductors
Stefanie Winkler,Stefanie Winkler,Patrick Amsalem,Johannes Frisch,Martin Oehzelt,Martin Oehzelt,Georg Heimel,Norbert Koch,Norbert Koch +8 more
TL;DR: In this article, a combined theoretical and multi-technique experimental approach was employed to understand the properties and dynamics of polarons in weakly interacting molecular systems, including inter-site Coulomb interaction between molecular ions and circumjacent neutral molecules, and provided a complete picture for the electronic structure of molecular semiconductors in the presence of excess charges.
Journal ArticleDOI
Space-Charge Transfer in Hybrid Inorganic-Organic Systems
Yong Xu,Oliver T. Hofmann,Raphael Schlesinger,Stefanie Winkler,Johannes Frisch,Jens Niederhausen,Antje Vollmer,S. Blumstengel,Fritz Henneberger,Norbert Koch,Norbert Koch,Patrick Rinke,Matthias Scheffler +12 more
TL;DR: D density functional theory calculations of hybrid inorganic-organic systems that explicitly include the global effects of doping (i.e., position of the Fermi level) and the formation of a space-charge layer are discussed.
Journal ArticleDOI
Surface Modification of ZnO(0001)–Zn with Phosphonate-Based Self-Assembled Monolayers: Binding Modes, Orientation, and Work Function
Melanie Timpel,Marco Vittorio Nardi,Stefan Krause,Giovanni Ligorio,Christos Christodoulou,Luca Pasquali,Angelo Giglia,Johannes Frisch,Berthold Wegner,Paolo Moras,Norbert Koch,Norbert Koch +11 more
TL;DR: In this paper, the authors used partially fluorinated alkyl and aromatic phosphonates as model systems with similar molecular dipole moments to form self-assembled monolayers (SAMs) on the Zn-terminated ZnO(0001) surface.
Journal ArticleDOI
Light‐Modulation of the Charge Injection in a Polymer Thin‐Film Transistor by Functionalizing the Electrodes with Bistable Photochromic Self‐Assembled Monolayers
Thomas Mosciatti,Maria G. del Rosso,Martin Herder,Johannes Frisch,Norbert Koch,Stefan Hecht,Emanuele Orgiu,Paolo Samorì +7 more
TL;DR: High fatigue resistance, bistability, and drastic property changes among isomers allow efficient modulation of the current output of organic thin-film transistors to be obtained by a photogating of the charge-injection mechanism.
