Vacuum-Processed Polyaniline-C60 Organic Field Effect Transistors

Vacuum-processed emeraldine base polyaniline is employed as gate insulating layer in organic field effect transistors. Both polyaniline and the small molecule semiconductor (i.e., C-60) layers are successively evaporated without breaking the vacuum in the evaporation chamber, suggesting the applicability of evaporation processes as industrial route for the fabrication of OFETs.
