General Electronic Model of the Interface
In this chapter we introduce a general basic understanding of the situation that electrons, which are moving through a crystal, find when they encounter a material interface. To stress an analogy from the world of theatre, in this chapter we prepare the stage and set up the scenery for the play called “electron transport”, which will be performed in the following chapters. The concept developed in this chapter will allow some statements to be made on the charge distribution at the interface. The influence of these charges on the electrostatic potential then will lead to the basic interface conditions for the Poisson equation.
