Suppose I want to solve the 1D, time-independent Schrödinger-equation for a metal-semiconductor junction.

In the metal region the Schrödinger equation reads:

(p^2/2m + V)ψ = Eψ

In the semiconductor region the Schrödinger equation reads:

(p^2/2m* + V + ΔESM)ψ = Eψ

My question is: Is there a way to "integrate out" the metal region or replace by an appropriate boundary condition at the metal-semiconductor interface?
