Schroedinger equation for metal / semiconductor

In summary, the Schrödinger equation is a mathematical formula that describes the behavior of particles in a quantum system, specifically electrons in metals and semiconductors. It helps us understand the electronic behavior of these materials by providing information about their energy levels and wave functions. The equation is derived from the principles of quantum mechanics and has been found to accurately predict the behavior of metals and semiconductors. It is commonly used in practical applications such as electronic device design and material development, as well as in computational simulations.

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?
