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⁻³N_v
(PositiveFloat) – Effective density of states in the valence band.
Units: cm⁻³E_g
(PositiveFloat) – Band gap energy.
Units: eV
Electron-hole Recombination Mechanisms#
Recombination mechanisms can include:
R
(List) – Array containing the recombination models to be applied to the material.
Optional Arguments#
delta_E_g
– Slotboom model for band-gap narrowingN_a
– Number of acceptor charges (holes). Units: cm⁻³N_d
– Number of donor charges (electrons).
Units: cm⁻³
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.
