Dynamic photoswitching of electron energy levels at hybrid ZnO/organic photochromic molecule junctions

Wang, Qiankun; Ligorio, Giovanni; Cabanes, Valentin Diez; Cornil, David; Kobin, Björn; Hildebrandt, Jana; Nardi, Marco Vittorio; Timpel, Melanie; Hecht, Stefan; Cornil, Jérôme; Kratochvil, Emil J. W. List; Koch, Norbert

The functionality of interfaces in hybrid inorganic/organic (opto)electronic devices is determined by the alignment of the respective frontier energy levels at both sides of the heterojunctions. Controlling the interface ...

Electronic Properties of Optically Switchable Photochromic Diarylethene Molecules at the Interface with Organic Semiconductors

Wang, Qiankun; Frisch, Johannes; Herder, Martin; Hecht, Stefan; Koch, Norbert

Light-switching induced changes in the electronic properties of photochromic diarylethene, i.e., 1,2-bis(2-methyl-5-p-tolylthiophen-3-yl)cyclopent-1-ene (DAE1), thin films at interfaces to a gold electrode and two polymer ...

Insights into Charge Transfer at an Atomically Precise Nanocluster/Semiconductor Interface

Wang, Yu; Liu, Xiao-He; Wang, Qiankun; Quick, Martin; Kovalenko, Sergey A.; Chen, Qing-Yun; Koch, Norbert; Pinna, Nicola

The deposition of an atomically precise nanocluster, for example, Ag44(SR)30, onto a large‐band‐gap semiconductor such as TiO2 allows a clear interface to be obtained to study charge transfer at the interface. Changing the ...
