ChargeTransport.jl – Simulating charge transport in semiconductors

Build status DOI

ChargeTransport.jl simulates charge transport in semiconductors. To this end, it discretizes the semiconductor drift-diffusion equations via the Voronoi finite volume method as implemented in VoronoiFVM.jl.

Special features

  • heterostructures
  • 1D, 2D and 3D simulations
  • stationary and transient simulations
  • IV curves and scan protocols
  • an arbitrary amount of charge carriers may be added
  • thermodynamically consistent, physics preserving numerical methods
  • different charge carrier statistics per species (Boltzmann, Blakemore, Fermi-Dirac)
