Low-temperature characterization of organic conducting thin films

Conducting polymer thin films were investigated at low temperatures. We present results for such a spin coated film made of poly[2-methoxy-5-(2'-ethylhexyloxy)-p-phenylene vinylene] (MEH-PPV) which was tested for temperatures below 20 \r{ }C. The film was probed over several cycles of cooling then heating. For each cycle the results showed a similar temperature dependent resistance. Such polymer thin films have potential applications as flexible temperature sensors.
