Sensor Materials

Simon Spannagel requested to merge materials into master

This MR adds the possibility of simulating other sensor materials than silicon. For now we have GaAs implemented and validated thanks to @psmolyan but others might follow before this gets merged.

Right now this essentially is a new parameter for the detector model,

sensor_material = "silicon"

which is checked against a list of known materials. I prefer this over just using whatever material from the NIST database, because I might want to implement additional checks down the line - and otherwise you can quickly get very odd results by just selecting whatever material.

The material currently is only used in the GeometryBuilderGeant4 module to construct the correct sensor material for interaction with the incident radiation.

Other places where it might be useful:

  • Do we want to provide a list of ionization energies and Fano factors?
  • Does it makes sense to add material checks to all mobility/recombination/... models or do we leave this to the user to select properly?
  • We should add a dedicated section to the user manual pointing out the necessary settings to e.g. get a proper GaAs simulation running

This fixes #109 (closed)
