Revision of the standard hydrodynamic transport model for SOI simulation

Anomalous output characteristics are observed in hydrodynamic simulations of partially depleted SOI MOSFETs. The effect that the drain current reaches a maximum and then decreases is peculiar to the hydrodynamic transport model. It is not observed in drift-diffusion simulations and its occurrence in measurements is questionable. An explanation of the cause of this effect is given and a solution is proposed by modifying the hydrodynamic transport model.
