3.1 Introduction

An important aspect of opto-electronic engineering is the alloy concentration dependence of the bandgap of semiconducting alloys. By the control of alloy concentration, the appropriate optical response can be engineered for complex thin film structures. Another aspect that can contribute to the optical response involves deviations from stoichiometry of the compound. In general, stoichiometry deviations are related to defects or impurities. ...
