Organic Electronics Part I: Chemical Modulation

Organic semiconductors (OS) have been in the center of attention in at least two areas: in chemical ,sensors and in molecular electronics. Although the chemistry and physics governing them is the same their performance characteristics are apparently measured on different scales. Electrochemical sensors operate on the principle of controlled change of some electrical parameter, e.g. conductivity, current or voltage, caused by the change of the chemical environment. Specifically, in electrochemical gas sensors the change of conductivity or work function is measured in response to the change of partial pressure of the analyte. On the other hand, in molecular electronic applications the effect of these “environmentalâ€? factors are either ignored or generally seen as a nuisance that should be... Show More
