tidy3d.ShockleyReedHallRecombination#

class ShockleyReedHallRecombination[source]#

Bases: Tidy3dBaseModel

Defines the parameters for the Shockley-Reed-Hall (SRH) recombination model.

Parameters:

Notes

The recombination rate parameter from this model is defined from [1] as follows:

\[R_{SRH} = \frac{n p - n_0 p_0}{\tau_p \left(n + \sqrt{n_0 p_0}\right) + \tau_n \left(p + \sqrt{n_0 p_0}\right)}.\]

Note that the electron and holes densities are defined within the SemiconductorMedium. The electron lifetime \(\tau_n\) and hole lifetimes \(\tau_p\) need to be defined.

Example

>>> import tidy3d as td
>>> default_Si = td.ShockleyReedHallRecombination(
...   tau_n=3.3e-6,
...   tau_p=4e-6,
... )

Note

Important considerations when using this model:

  • This model represents mid-gap traps Shockley-Reed-Hall recombination.
