Improved Electrical Properties of EHD Jet-Patterned MoS₂ Thin-Film Transistors with Printed Ag Electrodes on a High-k Dielectric.

ABSTRACT: Electrohydrodynamic (EHD) jet printing is known as a versatile method to print a wide viscosity range of materials that are impossible to print by conventional inkjet printing. Hence, with the understanding of the benefits of EHD jet printing, solution-based MoS₂ and a high-viscosity Ag paste were EHD jet-printed for electronic applications in this work. In particular, printed MoS₂ TFTs with a patterned Ag source and drain were successfully fabricated with low-k silica (SiO₂) and high-k alumina (Al₂O₃) gate dielectrics, respectively. Eventually, the devices based on Al₂O₃ exhibited much better electrical properties compared to the ones based on SiO₂. Interestingly, an improvement of around one order of
