Doping of P3HT was employed to accumulate and tune the carrier concentration while implementation of depletion layer led to reduce the channel conductance. It has been demonstrated that on-currents in the OFETs were enhanced with the extent of TCNQ doping from 0% to 20% in the P3HT. Upon introduction of an ultra-thin Al led to the formation of depletion region resulting in to further decrease in the off-state current along with the improvement in the subthreshold characteristics. These two procedures provide counter-effects in terms of the on-state characteristics by doping and the off-state characteristics by depletion, which promotes switching performance in OFETs indicating the potentiality of doping technology for organic electronics.}, pages = {152--158}, title = {Implications of doping and depletion on the switching characteristics in polymer-based organic field-effect transistors}, volume = {56}, year = {2018}, yomi = {タカシマ, ワタル and ナガマツ, シュウイチ and ハヤセ, シュウジ} }
