2.13. currents{ }

Calling sequence

currents{ }

Properties

• usage: \(\mathrm{\textcolor{ForestGreen}{optional}}\)

• items: maximum 1

Dependencies

• insulator_bandgap is not allowed if any of import_electron_fermi_level{ } or import_hole_fermi_level{ } is already defined.

Functionality

Presence of this group is required to run solver of the current equation. Keywords contained allow selecting mobility and recombination models for the drift-diffusion model of currents, as well as to control some numerical aspects of the related solver and outputs.

Examples

currents{
    recombination_model{}
}

currents{
    recombination_model{}
    insulator_bandgap = 0.5
}

currents{
    recombination_model{}
    import_electron_fermi_level{}
    import_hole_fermi_level{}
}

currents{
    recombination_model{}
    minimum_density_electrons = 1e-5
    minimum_density_holes = 1e-7
