Semiconducting single-walled carbon nanotubes (SWCNTs) have fascinating optical and electronic properties. They exhibit very high carrier mobilities and can be processed from solution. These characteristics make them highly interesting for novel (opto)electronic devices such as electrochemical transistors. Here, we want to explore the distribution of ions and charge carriers in electrochemically gated thin films of polymer-wrapped SWCNTs through high-resolution Raman- and photoluminescence microscopy and compare them with semiconducting polymers and composites of both materials. In collaboration with the other groups within the RTG, we further aim to modify and pattern SWCNT networks to apply them in sensors and actuators 

This project requires a background in physical chemistry, nano- or materials science. It involves solution-based material processing, device fabrication in a cleanroom, and electrical characterization in combination with advanced spectroscopy and microscopy techniques.
