minimum_density_factor¶

Calling sequence

currents{ minimum_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 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.
