PDE - Contact Resistance

Hi Everyone,
I am wondering how to implement electrical or thermal contact resistance when using the PDE physics.
I am using the PDE coefficient form to model thermoelectric effects at a metal-semiconductor interface. I have a working thermoelectric model, but I want to include the effects of contact resistance at the interface.
I am aware the Heat Transfer physics has a "Thin Thermally Resistive Layer" which introduces a resistance to heat flow and a discontinuity in the temperature at a boundary. However, I have been unable to simulate a similar interface resistance using PDE physics.
I am using COMSOL 4 and I appreciate any help anyone can provide.
Thank you,
- Kyle
