Allow definition of 3D sensor implants
Allow the definition of pixel implants in the sensor to be able to only collect charges from the implants instead of the full sensor surface. Ideas/guidlines:
-
Implants should be part of the detector model -
Implant sizes should not be defined by default as they vary a lot depending on the sensor/vendor/... -
In the propagation, implant positions can be used as cut-off criteria (conductor...) -
In the transfer module, there should be a switch to turn on/off collection only from the implant region or the full sensor surface -
In the transfer module, there should be a check: - it only makes sense to use implant regions with a TCAD field, with a linear field it's nonsensical.
- an error should be thrown in case a combination of
[switch, field, implants]
is supposed to be used which does not make sense - this way the simulation is transparent and the user is informed about what's going on
This feature would be nice to have for the first release as it allows to show the difference in collecting charge with a small and a large implant.
