currents{ minimum_density_factor }¶
\(\mathrm{\textcolor{Aquamarine}{optional}}\)
type: \(\mathrm{vector\;of\;2\;real\;numbers}\)
unit: \(\mathrm{-}\)
values: \([0.0, \ldots)\;\mathrm{for\;each\;dimension}\)
default: \([1.0\;1.0]\)
The two numbers of minimum_density_factor
are scaling factors by which the minimum density \(\rho_\mathrm{min}\) (see currents{ 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.
- Example:
A minimum density of \(10^{10}\;\mathrm{cm}^{-3}\) for electrons and \(10^{8}\;\mathrm{cm}^{-3}\) for holes can be defined as
minimum_density = 1e10 # [cm^-3] minimum_density_factor = [1.0 , 0.01] # [-]
or
minimum_density = 1e9 # [cm^-3] minimum_density_factor = [10 , 0.1] # [-]
or explicitly as
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.
