tidy3d.SteadyChargeDCAnalysis#

class SteadyChargeDCAnalysis[source]#

Bases: Tidy3dBaseModel

Configures relevant steady-state DC simulation parameters for a charge simulation.

Parameters:

tolerance_settings (ChargeToleranceSpec = ChargeToleranceSpec()) – Charge tolerance parameters relevant to multiple simulation analysis types.
convergence_dv (PositiveFloat = 1.0) – Maximum bias step used to aid convergence in DC computations. The accelerated solver applies it only to multi-voltage sweeps: where the gap between consecutive sweep voltages exceeds convergence_dv, intermediate warm-start bias points are inserted (and excluded from the output); a single-voltage simulation is solved directly. The legacy solver instead ramps every requested bias from 0 in convergence_dv increments.
fermi_dirac (bool = False) – Determines whether Fermi-Dirac statistics are used. When False, Boltzmann statistics will be used. This can provide more accurate results in situations where very high doping may lead the pseudo-Fermi energy level to approach either the conduction or valence energy bands.
