**Meet the editor**

Dr. Vasilios N. Stavrou is currently an Adjunct Member at the Hellenic Naval Academy, Pireus, Greece. He received his MSc and PhD in Theoretical Solid State Physics from the University of Essex in England, in 1995 and 1999 respectively. As a postdoctoral researcher, he worked at the following institutes: Deutsche Forschungsanstalt fuer Luft und Raumfahrt e.V (German Aerospace Research Center) in Germany; State University of New York (SUNY) at Buffalo, USA; and University of Iowa, USA. His research interests are related to quantum computing, spintronics, decoherence in quantum dots, diluted magnetic semiconductors, and phonon models in low dimensional structures among others. The results of his work have been published in reputable journals and were also presented at a number of International Conferences.

## Preface

Semiconductor quantum dots are small devices in which carriers exhibit strong three dimen‐ sional confinement and show discrete energy spectrum. Their tunable optical and electronic properties enable them to be used in several optoelectronic / electronic devices such as quantum bits, sensors, and lasers among others. In this book, a few theoretical aspects and applications are included.

The current book is divided in two sections. In the first section, fundamental theories on excitons, trions, phase decoherence, and charge states are presented. Several applications of quantum dots are included in the second section.

As the editor of this book project, I would like to thank all the authors for their contributions and efforts to bring the up-to-date research of their high quality work.

Lastly, I gratefully acknowledge the InTech team for their support during the preparation of the book.
