Schnelle Rasterkraftmikroskopie durch moderne Regelungstechnik und mechatronische Systemintegration

In atomic force microscopy (AFM) high-performance and high precision control of the scanning-system is crucial. At high imaging speeds the dynamic behaviour of the scanner may cause imaging artefacts limiting the maximum imaging rate. This contribution discusses recent improvements for faster imaging by utilizing modern mechatronic and control...

Synthesis, Mesophase Behaviour and Charge Mobility of Phenyl-Thiophene Pentamers

The performance of opto-electronic devices based on semi-conducting organic molecules, dependence on the molecular order of the semi-conducting molecules. To get high charge transportation through the material a high order of the material is needed. In our research we used liquid crystalline phases to get relative high order over large distances...
