OSE6314 - Optics of Low Dimensional Semiconductors
This is a single semester course designed to strengthen the knowledge base of graduate students in the physics and fabrication
of low dimensional semiconductors. The first portion of the course is spent reviewing and expanding the fundamental solid
state and quantum mechanical principles that are used to describe the optical and electrical properties of low dimensional
heterostructures. This is then transitioned into real quantum well heterostructures and quantum dots, with additional emphasis
on the different subsets and fabrication methods. The final portion of the course introduces some of the modern novel nanophotonic
devices that exploit the unique properties of low dimensional semiconductor structures.
