Did you use periodic boundary conditions in yz plane?

please extend the device outside of the PBCs, or reduce the periodicity if there is no other nano particles.

In additiotn, such device requires long simulation and proper mesh size. Please significantly increase the simulation time , such as 100 times longer than the current settings, and at the same time, reduce the autoshutoff min two orders smaller, eg 1e-7 or smaller. and redo the simulation.


You can also use stackrt to get analyticalsoultions:stackrt - Script command which works onlt for thin-film type devices.
