maximum_density_factor¶

Calling sequence

currents{ maximum_density_factor }

Properties

using: \(\mathrm{\textcolor{ForestGreen}{optional}}\)
type: \(\mathrm{vector\;of\;2\;real\;numbers}\)
values: \([0.0, \ldots)\;\mathrm{for\;each\;dimension}\)
default: \([1.0,\;1.0]\)
unit: \(\mathrm{-}\)

Functionality

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

Examples

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

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

or

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

or explicitly as

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

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