Current transients in organic field effect transistors.

In this work the detailed charging and extraction current transients in the channel of organic field effect transistors are presented. This allows for precise estimation of the charge carrier mobility along the channel and in the direction perpendicular to the layer. The charge carrier mobility is experimentally obtained by various methods: from the extraction transients (in small charge and space charge limited current modes) as well as from the duration of the gate charging. The results are in good agreement with the results obtained by steady state current, photogenerated carrier extraction by linearly increasing voltage, and time-of-flight. [ABSTRACT FROM AUTHOR]
