Zaumseil Group - Research Carbon-based semiconductors for sensors, circuits and energy conversion

Organic small molecule and polymer semiconductors as well as semiconducting single-walled carbon nanotubes (SWCNTs) are intriguing alternatives to conventional inorganic semiconductors (e.g., silicon) for many applications and devices that require mechanical flexibility and low-temperature processing (e.g., from solution). They also offer a wide range of unique and tunable optical and electronic properties that can be applied for sensors, conformal circuits or for energy conversion (e.g., thermoelectrics). We focus on investigating charge transport in these materials under different environmental conditions, at high and low temperatures, and deposited with selected methods (e.g., aerosol jet printing, zone-casting) to gain a better understanding of their structure-property relationships and to improve their performance.
