2 What is currently included?

\(\mathtt{\require{color}{\color[rgb]{0.000000000000000,0.500000000000000,0.500000000000000} SIMsalabim}}\) does not claim to capture all the physics of any specific semiconductor device. It is the sole responsibility of the user to assess whether this simulation is applicable or not. Thus, it is crucial to understand what is included and what is not. The current version of \(\mathtt{\require{color}{\color[rgb]{0.000000000000000,0.500000000000000,0.500000000000000} SIMsalabim}}\) includes the following: 1

  • Steady-state or fully transient simulations

  • Arbitrarily many layers can be specified

  • Mobile ionic species

  • Doping

  • Contacts are defined by their work function. The surface recombination velocities can be either finite or infinite.

  • Trapping, multiple trap levels can be defined.

  • Interfaces:

    • offsets in conduction and valence bands

    • differences in effective density-of-states

    • differences in dielectric constant

    • trapping and recombination

  • Generation of free charges:

    • Different profiles

      • Constant

      • Generated optical absorption profile based on the device structure

      • User-defined optical absorption profile

    • either direct or Onsager-Braun

  • Recombination processes:

    • direct, band-to-band recombination

    • trap-assisted recombination

    • interface recombination

    • geminate recombination

  • Series and shunt resistances

  • Tracking of open-circuit voltage (\(\mathtt{\require{color}{\color[rgb]{0.000000000000000,0.500000000000000,0.500000000000000} ZimT}}\))

  1. Future versions may include/refine/modify the implemented physics.
