output_fermi_levels{} (optional)

prints out the Fermi levels for electrons and holes [eV]

output_fermi_level_differences{} (optional)

prints out the difference of electron and holes Fermi levels, \(\Delta E_ \text{F} = E_{\text{F,n}} - E_{\text{F,p}}\) [eV] By overlaying the Fermi level difference over the band gaps, you may e.g. determine where and involving which bands lasing may occur.

output_mobilities{} (optional)

prints out the electron and hole mobilities [cm^2/Vs]

output_recombination{} (optional)

prints out the recombination rates [1e18/(cm^3s)]


If you want to output the generation rate, you have to specify this in structure{region{generation{}}} ==> output_generation{} }.

boxes (optional)

For each grid point, in 1D two points are printed out to mimic abrupt discontinuities at interfaces (in 2D four points, in 3D eight points)




= yes or no

output_currents{} (optional)

prints out the electron and hole current densities [A/cm^2]


The electron, hole, and total currents (integrated over the contacts surfaces) are always written into the files IV_electrons.dat, IV_holes.dat, and IV_characteristics.dat (in units of [A/cm^2] (1D), [A/cm] (2D), [A] (3D)), respectively. If radiative recombination is used, the file IV_characteristics.dat also contains the photo current. In all IV_*.dat files, the first columns indicate the voltages at each contact. Typically, the first column should be the one that is swept as it is then easier to plot the results within nextnanomat as the first column is the x axis in such a plot. You can switch the columns by reordering the contacts, see contacts{}. The consumed power is written in IV_Power.dat in units of [W/cm^2] (1D), [W/cm] (2D), [W] (3D), respectively. The emitted power column is added if the energy resolved density integration is enabled.

output_velocities{} (optional)

prints out electron and hole drift velocities [cm/s]

output_forces{} (optional)

prints out driving forces of electrons and holes [eV/nm]

output_power_density{} (optional)

prints out power density (only Joule heating) [W/cm^3]
