tidy3d.ShockleyReedHallRecombination#
- class ShockleyReedHallRecombination[source]#
Bases:
Tidy3dBaseModelDefines the parameters for the Shockley-Reed-Hall (SRH) recombination model.
- Parameters:
tau_n (Union[PositiveFloat,
FossumCarrierLifetime]) – [units = sec]. Electron lifetimetau_p (Union[PositiveFloat,
FossumCarrierLifetime]) – [units = sec]. Hole lifetime
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.
