Controlling Single Molecule Conductance by a Locally Induced Chemical Reaction on Individual Thiophene Units

Klaus Kern, Uta Schlickum, Hagen Klauk, Peter Wahl, Ivan Pentegov, Verena Katharina Schendel

Among the prerequisites for the progress of single-molecule-based electronic devices are a better understanding of the electronic properties at the individual molecular level and the development of methods to tune the charge transport through molecular jun ...

Remotely Controlled Isomer Selective Molecular Switching

Klaus Kern, Uta Schlickum, Hagen Klauk, Peter Wahl, Ivan Pentegov, Verena Katharina Schendel

Non local addressing-the "remote control"- of molecular switches promises more efficient processing for information technology, where fast speed of switching is essential. The surface state of the (111) facets of noble metals, a confined two-dimensional el ...

Bipolar Conductance Switching of Single Anthradithiophene Molecules

Klaus Kern, Uta Schlickum, Hagen Klauk, Peter Wahl, Ivan Pentegov, Verena Katharina Schendel

Single molecular switches are basic device elements in organic electronics. The pentacene analogue anthradithiophene (ADT) shows a fully reversible binary switching between different adsorption conformations on a metallic surface accompanied by a charge tr ...

Separating the impact of oxygen and water on the long-term stability of n-channel perylene diimide thin-film transistors

Klaus Kern, Hagen Klauk, Ralf Thomas Weitz

A detailed understanding for the mechanisms that control degradation of the electrical performance of organic thin-film transistors (TFTs) during exposure to various environments, such as oxygen and humidity, is still developing. This is particularly true ...

High-Performance ZnO Nanowire Transistors with Aluminum Top-Gate Electrodes and Naturally Formed Hybrid Self-Assembled Monolayer/AlOx Gate Dielectric

Klaus Kern, Hagen Klauk, Frederik Sebastian Ante

A method for the formation of a low-temperature hybrid gate dielectric for high-performance, top-gate ZnO nanowire transistors is reported. The hybrid gate dielectric consists of a self-assembled monolayer (SAM) and an aluminum oxide layer. The thin alumin ...

High-mobility organic thin-film transistors based on a small-molecule semiconductor deposited in vacuum and by solution shearing

Klaus Kern, Hagen Klauk

The small-molecule organic semiconductor 2,9-di-decyl-dinaphtho-[2,3-b: 2',3'-f]-thieno[3,2-b]-thiophene (C-10-DNTT) was used to fabricate bottom-gate, top-contact thin-film transistors (TFTs) in which the semiconductor layer was prepared either by vacuum ...

Contact properties of high-mobility, air-stable, low-voltage organic n-channel thin-film transistors based on a naphthalene tetracarboxylic diimide

Klaus Kern, Hagen Klauk

Air-stable bottom-gate, top-contact n-channel organic transistors based on a naphthalene diimide exhibiting electron mobilities up to 0.8 cm(2)/Vs at low voltages were fabricated. Transistors with channel lengths of 1 mu m show a transconductance of 60 mS/ ...

Probing the electrical properties of highly-doped Al:ZnO nanowire ensembles

Klaus Kern, Hagen Klauk

The analysis of transparent conducting oxide nanostructures suffers from a lack of high throughput yet quantitatively sensitive set of analytical techniques that can properly assess their electrical properties and serve both as characterization and diagnos ...
