摘要：

We have developed analytical model for subthreshold swing of cylindrical gate MOSFETs using analytical solution of 2D Poisson's equation and evanescent mode analysis. To account doping effect in subthreshold swing an effective conducting path R-eff is introduced in this model. The parameter R-eff presents the location of S-weighted of subthreshold conduction. By comparison with different published results, the conventional model shows an overestimation of subthreshold swing while our model reveals quantitative agreement.
