• \(\mathrm{\textcolor{Aquamarine}{optional}}\)

• 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 maximum_density_factor are scaling factors by which the maximum density \(\rho_\mathrm{max}\) (see currents{ 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.

Example:

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

maximum_density        = 1e10            # [cm^-3]
maximum_density_factor = [1.0 , 0.01]    # [-]

or

maximum_density        = 1e9             # [cm^-3]
maximum_density_factor = [10 , 0.1]      # [-]

or explicitly as

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.
