Abstract

The low frequency (1f) noise in single SnO₂ nanowire transistors was investigated to access semiconductor-dielectric interface quality. The amplitude of the current noise spectrum (S_I) is found to be proportional to I_d² in the transistor operating regime. The extracted Hooge's constants (α_H) are 4.5×10 ^-2 at V_ds=0.1 V and 5.1×10^-2 at V _ds=1 V, which are in general agreement with our prior studies of nanowire/nanotube transistors characterized in ambient conditions. Furthermore, the effects of interface states and contacts on the noise are also discussed.
