minimum_density_factor

Calling sequence

currents{ minimum_density_factor }

Properties

• usage: \(\mathrm{\textcolor{ForestGreen}{optional\;within\;the\;group}}\)

• type: \(\mathrm{vector\;of\;2\;real\;numbers}\)

• values: [0.0, ...) for every dimension

• default: [1.0, 1.0]

• unit: \(\mathrm{-}\)

Functionality

The two numbers of minimum_density_factor are scaling factors by which the minimum density \(\rho_\mathrm{min}\) (see minimum_density) is multiplied for electron and for hole density distributions. The first number is scaling the \(\rho_\mathrm{min}\) for electrons, while the second number is scaling the \(\rho_\mathrm{min}\) for holes.

Examples

A minimum density of \(10^{10}\;\mathrm{cm}^{-3}\) for electrons and \(10^{8}\;\mathrm{cm}^{-3}\) for holes can be defined as

currents{
    recombination_model{}
    minimum_density = 1e10 # cm^-3
    minimum_density_factor = [ 1.0 , 0.01 ]
}

or

currents{
    recombination_model{}
    minimum_density = 1e9 # cm^-3
    minimum_density_factor = [ 10 , 0.1 ]
}

or explicitly as

currents{
    recombination_model{}
    minimum_density = 1.0  # cm^-3
    minimum_density_factor = [ 1e10 , 1e8 ]
}

Irrespective to the method of definition, the values used for the minimum densities are the same and output close to the beginning of the log file.
