Semiconductor module does t identifies materials as an insulator

Hello I am trying to model charge transport through a nanowire (semiconductor) on a glass substrate with the semiconductor model. Therefore I contacted the wire with two metal contact nodes and setting the voltage on one contact to 1 V and the other one to 0V; the material properties of the individual materials are set in local variables and are applied on the dedicated domains. But in my solution for the electric potential I can see that the potential drops over the wire and over the insulating material (glass) what does not make sense. Also I saw that comsol doesn't identifies the boundary between the wire and the glass substrate as an insulator interface.
is there a way I can define a domain or a material as an insulator ? Or am I completely on the wrong way?
