I will begin with a brief introduction to optical spectroscopy in semiconductors, emphasizing the analogy between impurities and excitations in semiconductors to aspects of atomic and particle physics. In this analogy, each semiconductor is a special vacuum in which the band gap energy is equivalent to the energy threshold for the production of an electron-positron pair in the real vacuum. ...
