All-Sputtering, High-Transparency, Good-Stability Coplanar Top-Gate Thin Film Transistors
In this work, transparent, stable coplanar top-gate thin film transistors (TFTs) with an active layer of neodymium-doped indium oxide and zinc oxide (Nd-IZO) were successfully fabricated on a glass substrate by all sputtering processes. The devices with a post-annealing temperature of 400 °C...

description | In this work, transparent, stable coplanar top-gate thin film transistors (TFTs) with an active layer of neodymium-doped indium oxide and zinc oxide (Nd-IZO) were successfully fabricated on a glass substrate by all sputtering processes. The devices with a post-annealing temperature of 400 °C exhibited good electrical performances with a saturation mobility (μsat) of 4.25 cm2·V−1·S−1, Ion/Ioff ratio about 106, Vth of −0.97 V and SS about 0.34 V/decade. Furthermore, the devices exhibited excellent negative and positive bias stability (NBS, PBS) of only a ΔVth shift of about −0.04 V and 0.05 V after 1 h, respectively. In addition, the devices showed high transparency about 96% over the visible-light region of 400–700 nm, which indicates a great potential in transparent displays. |
