Here, we report on the use of a graphene oxide (GO)/polystyrene (PS) bilayer as a gate dielectric for low-voltage organic field-effect transistors (OFETs). The hydrophilic functional groups of GO cause surface trapping and high gate leakage, which can be overcome by introducing a layer of PS—a hydrophobic polymer—onto the top surface of GO. The GO/PS gate dielectric shows reduced surface roughness and gate leakage while maintaining a high capacitance of 37.8 nF cm−2. The resulting OFETs show high-performance operation with a high mobility of 1.05 cm2 V−1 s−1 within a low operating voltage of −5 V.

AbstractThe molybdenum disulfide (MoS2)-based photodetectors are facing two challenges: the insensitivity to polarized light and the low photoresponsivity. Herein, three-dimensional (3D) field-effect transistors (FETs) based on monolayer MoS2 were fabricated by applying a self–rolled-up technique. The unique microtubular structure makes 3D MoS2 FETs become polarization sensitive. Moreover, the microtubular structure not only offers a natural resonant microcavity to enhance the optical field inside but also increases the light-MoS2 interaction area, resulting in a higher photoresponsivity. Photoresponsivities as high as 23.8 and 2.9 A/W at 395 and 660 nm, respectively, and a comparable polarization ratio of 1.64 were obtained. The fabrication technique of the 3D MoS2 FET could be transferred to other two-dimensional materials, which is very promising for high-performance polarization-sensitive optical and optoelectronic applications.
