Optical Spectroscopy in Semiconductors

---

Optical spectroscopy has been one of the most important tools for advancing our understanding of semiconductor physics and materials science, and it is an area in which Canada has a long and distinguished history. I will review my own experiences in this field, beginning with bound multiexciton complexes in silicon, and describing along the way aspects of double acceptors, compound semiconductors, alloys, heterostructures, and polyexcitons. Finally, I will explain how it is that after ~30 years I am excited to again be studying the fundamental properties of silicon.
