In this letter, flexible double-gate (DG) thin-film transistors (TFTs) based on InGaZnO4 and fabricated on free standing plastic foil, using self-alignment (SA) are presented. The usage of transparent indium-tin-oxide instead of opaque metals enables SA of source-, drain-, and top-gate ...

The ultrathin Al2O3 layer on IGZO showed a significant effect on enhancing the mobility, reducing the off-state current, and improving the gate-bias stability. As a result, the IGZO/Al2O3 bi-layer TFT eventually exhibited a saturation mobility of 18.5 cm2 V−1 s−1, an Ion/Ioff ...
Most thin-film transistor (TFT) gate drivers integrated on the display panel use the carry signals between the stages. In our previous works, we found that these carry-type gate drivers are subject to the reliability problem in a flexible display, since the errors of the stressed stages are ...

The stacked 3-T device configuration has 24 functional layers: a plastic substrate, seven conductor layers, three OSC layers, seven Parylene layers (one basement and six gate insulator films), three charge injection self-assembled monolayers, and three bank layers. For all the devices, the source...
Different from traditional rigid sensors based on silicon substrates, flexible sensors are suitable for irregularly shaped surfaces and complex measurement
The flexibility of material selection makes it possible to choose different polymers to prepare ionic-gel gate transistors. For most IGTs, polymer monomers are embedded into ionic solutions composed of polymer molecular segments, and the commonly used materials are mainly self-assembled tri-block and ...
(MWCNTs) decorated with self-assembled silver nanoparticles [81]. Silver nanoparticles (~3 nm) with phenyl rings are conjugated with MWCNTs via π-π interaction to produce nAg-MWCNTs and then mixed with silver flakes (Fig.7b,d). The nAg-MWCNTs form an effective electrical network among the ...
