In this paper, we present results on the electrical characteristics of both thick and thin film polymer metal–insulator–semiconductor field-effect transistors (MISFETs) based on poly(3-hexylthiophene) semiconducting substrate. These MISFETs were fabricated in eight steps using conventional semiconductor processing technology. The MISFETs had excellent current–voltage characteristics and showed little degradation with time. Electrical parameters of threshold voltage, mobility, and transconductance were − 1 V, 10−4–10−5 cm2 V−1 s−1, and 10−9 S, respectively. These values are typical of π-conjugated polymer-based MISFETs. Electrical transport in MISFETs were by both bulk (or resistive) and FET-like mechanisms in the thick film transistors. The resistive current component and the electrical characteristics were found to be tunable by photolytic degradation of the semiconducting polymer. In this process, the semiconducting π-conjugated regions were spatially converted to insulating regions by novel photo-oxidative chemistry. We were also successful in modelling the MISFETs as an intrinsic FET with parasitic source and drain resistances in series with it and a varistor (for the bulk current component) in parallel with the intrinsic FET. Using this circuit model, we obtained very good agreements between SPICE simulations and the experimental results.

AbstractMetal-insulator-semiconductor (MIS) structures are widely used in Si-based solar water-splitting photoelectrodes to protect the Si layer from corrosion. Typically, there is a tradeoff between efficiency and stability when optimizing insulator thickness. Moreover, lithographic patterning is often required for fabricating MIS photoelectrodes. In this study, we demonstrate improved Si-based MIS photoanodes with thick insulating layers fabricated using thin-film reactions to create localized conduction paths through the insulator and electrodeposition to form metal catalyst islands. These fabrication approaches are low-cost and highly scalable, and yield MIS photoanodes with low onset potential, high saturation current density, and excellent stability. By combining this approach with a p+n-Si buried junction, further improved oxygen evolution reaction (OER) performance is achieved with an onset potential of 0.7 V versus reversible hydrogen electrode (RHE) and saturation current density of 32 mA/cm2 under simulated AM1.5G illumination. Moreover, in stability testing in 1 M KOH aqueous solution, a constant photocurrent density of ~22 mA/cm2 is maintained at 1.3 V versus RHE for 7 days.
