The Failure of the Hydrodynamic Transport Model for Simulation of Partially Depleted SOI MOSFETs and its Revision

Gritsch M., Kosina H., Grasser T., Selberherr S., Linton T., Singh S., Yu S., Giles M.D., TU Vienna, AT

An anomalous output characteristics is 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 [...]

A Physics-Based Impact Ionization Model Using Six Moments of the Boltzmann Transport Equation

Grasser T., Kosina H., Gritsch M., Selberherr S., TU Wien, AT

Due to the ever decreasing device geometries non-local effects gain more and more importance. It is particularly well known that impact ionization is not properly described by neither a local field nor a local energy [...]
