- Abstract
- We report the random telegraph noise observed in gate-all-around (GAA) PMOS silicon nanowire FETs (SNWFETs) with the radius of 5 nm, at various temperatures (Ts) down to 4.2 K. From the T-dependence of the capture/emission time, we obtain the energy and the charging status of the trap states. The gate bias dependence and the T-dependence of the scattering coefficient-mobility product extracted from the relative fluctuation amplitude of the drain current are consistent with the fact that the surface roughness scattering is dominant in GAA PMOS SNWFETs.
