November 2009

219 pages

Description
At the intersection of semiconductor nanoscience and optics, this book provides an up-to-date introduction to the theory and methods of optically controlling spins in quantum dots.

Following an overview of the basic concepts of spin physics, this monograph describes fabrication methods of optically active quantum dots and their integration in electro-optic devices. Next, the theory of quantum-confined states is discussed, as well as spin-spin interactions and interaction with the radiation field. A review of key experimental techniques is given, highlighting recent results from the literature that demonstrate progress towards potential applications in spintronics and quantum information processing.

The result is a primer providing the essential basic knowledge necessary for young researchers entering the field. Additionally, this work -- encompassing theory, experiment, and materials science issues -- is a useful overview for specialists in this, or related fields.

About the Author
Oliver Gywat received his PhD in the group of Daniel Loss at the University of Basel, where he has worked on the theory of spin and entanglement in optically active quantum dots, focusing on implementations of quantum information schemes. He then was a postdoctoral research scholar in the group of David Awschalom at the California Nanosystems Institute and the Center for Spintronics and Quantum Computation at the University of California at Santa Barbara. After completing his postdoctoral research in the theoretical and the experimental domain, he moved into finance and is currently working in the area of Investment Services and Products at Credit Suisse Private Banking in Zurich, maintaining a strong interest in nanotechnology and nanoscale sciences.
Hubert Krenner received his PhD at the Walter Schottky Institute of the Technische Universitat Munchen in the groups of Gerhard Abstreiter and Jonathan Finley. After a two year stay as a Feodor Lynen Fellow of the Alexander von Humboldt Foundation in the group of Pierre Petroff at the University of California, Santa Barbara, he moved to the Universitat Augsburg where he continues his work on control and manipulation of spin and charge excitations in optically active nanostructures.
Jesse Berezovsky received his PhD at the University of California, Santa Barbara in the group of David Awschalom, and is currently a postdoctoral researcher at Harvard University. His research has focused on optically probing spin dynamics in nanocrystal quantum dots, as well as developing techniques for the optical readout and ultrafast manipulation of single spins in a quantum dot.
