Abstract

Channel access resistance (R_sd) effects on the charge carrier mobility (μ) and low-frequency noise (LFN) in a polymethyl-methacrylate (PMMA) passivated tin-oxide nanowire (SnO₂-NW) field effect-transistor were investigated. To this end, the Y function method was employed for direct electrical parameters extraction without R_sd influence. Numerical simulation was used to evaluate gate-to-channel capacitance (C_gc) accounting for the electrostatic gate coupling effects through PMMA passivation layer. Furthermore, LFN measurements were carried out to study the SnO₂/dielectrics interface. The carrier number fluctuation (CNF) noise model was found appropriate to interpret LFN data provided R_sd influence is included.
