The Vapour Sensing Capabilities of Organic Field-Effect Transistors [PDF]
The work in this doctoral thesis is mainly concerned with the detection of volatile organic vapours (analytes) using organic field-effect transistors (OFETs) as transducers, in some cases using a ‘sensitiser layer’ on top of the devices to improve their ...
