摘要
This work demonstrates the double-stacked nanosheet (NS) p-channel vertically junctionless field-effect transistors (VJ-FET) with gate all around (GAA) structure. The stacked NS device shows superior electrical properties, including high Ion/Ioff ratio , subthreshold slope (SS) =100mV/dec, and normally off at Vg=0V. More, this work also discusses three different gate structure in electrical properties. The 3D TCAD simulation is applied for analysis of physical characteristics of the proposed devices.
