6. Polyelectrolyte based organic field effect transistors
University essay from Institutionen för teknik och naturvetenskap; Tekniska högskolanAbstract : In this thesis work, the fabrication of dual gate organic field-effect transistors (DGOFETs) using polyanionic proton conductor named polyvinylphosphonic acid and acrylic acid P(VPA-AA), SiO 2 as gate insulating materials and poly(3-hexylthiophene) (P3HT) as organic semiconductor have been studied. Upon operation, the top insulating layer forms large electric double layer capacitors (EDLCs)at the Ti/P(VPA-AA) and P(VPAAA)/ P3HT interfaces. READ MORE
