D.1.2 The Model FNLenzlingerSnow

This model is a generalization of the FOWLER-NORDHEIM model by giving the electron mass in the dielectric as a physically-based fitting parameter. The current density is calculated by expression (3.118). Since the electron mass in the dielectric $\ensuremath{m_\mathrm{diel}}$ is usually given in terms of the free electron mass m$_0$, the fitting parameters is now the ratio $\ensuremath{m_\mathrm{diel}}/\mathrm{m}_0$. Table D.2 shows the model keywords.

The electron or hole barrier height $\ensuremath {\mathrm{q}}\ensuremath{\Phi_\mathrm{e}}$ or $\ensuremath {\mathrm{q}}\ensuremath{\Phi_\mathrm{h}}$ is calculated from the band edge energies and cannot be given in the input deck.
