Controlling Electron and Hole Charge Injection in Ambipolar Organic Field-Effect Transistors by Self-Assembled Monolayers
Xiaoyang Cheng,Yong-Young Noh,Yong-Young Noh,Jianpu Wang,Marta Tello,Marta Tello,Johannes Frisch,Ralf-Peter Blum,Antje Vollmer,Jürgen P. Rabe,Norbert Koch,Henning Sirringhaus +11 more
TL;DR: In this article, the authors showed that SAM electrode modification is able to improve both electron and hole injection in poly(9,9-di-n-octylfluorene-alt-benzothiadiazole) ambipolar OFETs using self-assembled monolayers.

Band bending in conjugated polymer layers.
Ilja Lange,James C. Blakesley,Johannes Frisch,Antje Vollmer,Norbert Koch,Norbert Koch,Dieter Neher +6 more
TL;DR: The Kelvin probe method is used to study the energy-level alignment of four conjugated polymers deposited on various electrodes to show that the energetic spread of these states is correlated with charge-carrier mobilities, suggesting that the same states also govern charge transport in the bulk of these polymers.

High Fill Factor and Open Circuit Voltage in Organic Photovoltaic Cells with Diindenoperylene as Donor Material
Julia Wagner,Mark Gruber,Alexander Hinderhofer,Andreas Wilke,Benjamin Bröker,Johannes Frisch,Patrick Amsalem,Antje Vollmer,Andreas Opitz,Norbert Koch,Frank Schreiber,Wolfgang Brütting +11 more
TL;DR: In this article, small-molecule photovoltaic cells using diindenoperylene (DIP) as a new donor material in combination with the fullerene C 60 as an electron acceptor are demonstrated.
Surface effects in the Ni 2p x-ray photoemission spectra of NiO
TL;DR: In this paper, experimental and theoretical evidence of surface effects in the Ni $2p$ x-ray photoemission spectra (XPS) of NiO is reported. But the results are discussed in terms of bulk octahedral and surface-pyramidal Ni symmetries.

Controlling the work function of ZnO and the energy-level alignment at the interface to organic semiconductors with a molecular electron acceptor
Raphael Schlesinger,Yong Xu,Oliver T. Hofmann,Stefanie Winkler,Johannes Frisch,Jens Niederhausen,Antje Vollmer,S. Blumstengel,Fritz Henneberger,Patrick Rinke,Matthias Scheffler,Norbert Koch,Norbert Koch +12 more
TL;DR: In this paper, the authors show that the work function of ZnO can be increased by up to 2.8 eV by depositing the molecular electron acceptor 2,3,5,6-tetrafluoro-7,7,8,8-tetracyanoquinodimethane (F4TCNQ).
