This analysis was performed in accumulation regime, as a first step, addressing bias-dependency of various key MOSFET parameters (e. g. series resistance, channel width and gate-channel capacitance), non-uniform electron density due to corners and quantization. A significant bias-dependent series resistance variation in JL MOSFETs is reported above flat-band, leading to a significant mobility extraction accuracy drop of similar to 50%. All quasistationary device simulations were done on 100 nm long channel devices with 5-20 nm NW width, 2 nm SiO2 gate oxide thickness and 1x10(19) cm(-3) n-type channel doping using a constant mobility model (100 cm(2)/V.s).Si nanowireMulti-gateMobility extractionCorner effectJunctionlessAccumulationTCAD simulationtext::conference output::conference proceedings::conference paper
