Hi,nThe settings you shared seem fine. In your results, do you see the current increasing around when the voltage is turned on? If yes, this might not be related to the transient simulation settings. You can further examine by running a steady-state simulation (and have the voltage changed) and see if the change in carrier concentration matches your expectations there. This should be helpful for better understanding where the issue is coming from. Please let me know if there are updates or if you have further questions.nKind regardsn
