Tips

Radiation damage

Surface damage

To add surface charge, add the lines below to sdevice_des.cmd file.

Physics(MaterialInterface="Oxide/Silicon"){
    Charge(Conc=1e12)
}

Free electrons inside silicon bulk are attracted by these positive charges.
Using visualize, you can see the electron accumulation near surface.
