Dielectric spectroscopy characterization reveals it has low leakage current and rather high breakdown voltage. Both n-channel and p-channel organic field effect transistors are fabricated using pentacene and fullerene as active layers. Both devices show device performances with lack of hysteresis, very low threshold voltages and high on/off ratios. Excellent film formation property is utilized to make AlO(x) and thin PVT bilayer in order to decrease the operating voltage of the devices. All solution processed ambipolar device is fabricated with simple spin coating steps using poly(2-methoxy-5-(2-ethyl-hexyloxy)-1,4-phenylenevinylene) (MEH-PPV) end capped with polyhedral oligomeric silsesquioxanes (POSS) as active layer. Our investigations show that PVT can be a very promising dielectric for organic field effect transistors.eninfo:eu-repo/semantics/closedAccessMaterials sciencePhysicsPolyvinyl triazoleDielectricOrganic field effect transistorPentaceneC(60)Thin-film transistorsGate insulatorPoly-1-vinyl-1,2,4-triazoleSemiconductorsHysteresisElectronAluminum compoundsDielectric materialsHeterojunction bipolar transistorsLeakage currentsThreshold voltageTransistorsDevice performanceHigh breakdown voltageLow threshold voltageLow-leakage currentPentacenesPoly (1-vinyl-1 ,2 ,4-triazole)Polyhedral oligomeric silsesquioxanesPolyvinyl triazoleOrganic field effect transistorsArticle0002873228000152-s2.0-7895148516649750312323794963Materials science, multidisciplinaryPhysics, applied1-Vinyl-1,2,4-Triazole; Arabinogalactans; Copolymers
