Abstract
We compare III-V nanowire (NW) metal-oxidesemiconductor field-effect transistors (MOSFETs) in a vertical gate-all-around (GAA) as well as a lateral trigate architecture with planar reference MOSFETs and reveal that the NW geometry does not deteriorate the low-frequency noise (LFN) performance. In fact, with gate oxides deposited at the same conditions, the NW structures show potential to achieve better metrics due to slightly lower border trap densities Nbt. The normalized LFN in transistors with a higher number of NW can degrade due to averaging effects between individual nanowires within the same device.
