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 (SI) is found to be proportional to Id2 in the transistor operating regime. The extracted Hooge's constants (αH) are 4.5×10 -2 at Vds=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.
