2.5.13. currents{ }

Calling sequence

currents{ }

Properties

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

• items: \(\mathrm{maximum\;1}\)

Dependencies

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

• minimum_density and maximum_density are required if minimum_density_factor and maximum_density_factor are already defined, respectively.

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{}
}
