In this paper, a short-channel threshold voltage model is presented for triple-material double-gate(TM-DG) MOSFET with uniform doping profile in the channel region. To obtain the channel potential expression, the two-dimensional (2D) Poisson’s equation has been solved using the parabolic potential approximation with suitable boundary conditions. Subsequently, the surface potential expression has been employed to derive an analytical expression of thresholod. The threshold voltage variation with various device parameters has been shown. To validate the model, ATLASTM based numerical simulation results have been used. |
