A quantum-mechanical compact model of the threshold voltage for quantum-wire (QW) MOSFETs has been developed. This approach is based on analytical 2D solutions for the decoupled Schrödinger and Poisson equations solved in a 2D cross-section of the silicon channel. A quantum correction based on the perturbation theory has been also introduced to improve the model accuracy. Finally, the validity of the model has been verified by comparison with data obtained with a 2D/3D Poisson-Schrödinger drift-diffusion simulation code.
