CHARGE needs semicodutor materials. metals are simplied to be PEC which is not included in the simulation. Vacuum is "Insulator" as it is not semicoductor. Insulator does not allow any charger passing. If it is used for tunneling, you may need to modify it into light semicondutor https://optics.ansys.com/hc/en-us/articles/360034919133-Tips-for-creating-a-new-semiconductor-material
