Connect different material with different Band Gap

  1. May 17, 2015 #1
    As you know AlGaAs and GaAs have different band gap).I want to know what will happen when we connect both of them to each other?
    In this figure I don't know how can we draw the jump in their junction.
    Could you tell me what does fermi level do?
