MINIMOSNT accounts for selfheating effects in semiconductor
devices by solving the lattice heat flow equation
selfconsistently with the DD or HD
transport equations, forming together a system of four, or respectively six,
partial differential equations.

are the mass density, specific heat, and
thermal conductivity of the respective materials.
The model for the heat generation, , depends on the
transport model used. In the driftdiffusion case equals the
