Charge

A semiconductor material is specified using the MultiPhysicsMedium, by setting its charge property to a SemiconductorMedium. The required parameters for the SemiconductorMedium are:

Density of States and Band Gap Energy#

  • N_c (PositiveFloat) – Effective density of states in the conduction band.
    Units: cm⁻³

  • N_v (PositiveFloat) – Effective density of states in the valence band.
    Units: cm⁻³

  • E_g (PositiveFloat) – Band gap energy.
    Units: eV

Electron-hole Recombination Mechanisms#

Recombination mechanisms can include:


Optional Arguments#

The free carrier densities can be either a float number or a doping box object.

For a practical example, please refer to this example notebook.
