Description
Summary:Amorphous oxide semiconductor transistors with a high current density output are highly desirable for large-area electronics. In this study, wrapping amorphous indium-gallium-zinc-oxide (a-IGZO) transistors are proposed to enhance the current density output relative to a-IGZO source-gated transistors (SGTs). Device performances are analyzed using technology computer-aided design (TCAD) simulations. The TCAD simulation results reveal that, with an optimized device structure, the current density of the wrapping a-IGZO transistor can reach 7.34 μA/μm, representing an approximate two-fold enhancement compared to that of the a-IGZO SGT. Furthermore, the optimized wrapping a-IGZO transistor exhibits clear flat saturation and pinch-off behavior. The proposed wrapping a-IGZO transistors show significant potential for applications in large-area electronics.
