About the book

First proposed by Prof. Yakov Frenkel in 1931, the exciton is an electrically neutral quasiparticle consisting of an electron and a hole held together by electrostatic forces and is responsible for energy transport in organic molecular crystals. The Frenkel exciton has a typical radius of 1 nm and binding energy in the range of 0.1-1.0 eV. The Wannier- Mott exciton named after Prof. Gregory Wannier and Prof. Neville Francis Mott has a larger radius of about 10 nm and binding energy of 0.01 eV that is often used to explain energy transport in semiconductors having small energy gaps and a high dielectric constant. Various interactions namely exciton-exciton annihilation and exciton-polaron interactions are used to explain the optoelectronic properties of molecular crystals, semiconductors, quantum dots, graphene films, and carbon nanotubes. More importantly, a deeper understanding of the exciton theory has resulted in technological advances such as quantum dot lasers and LED’s with enhanced intensity and tunable emission wavelengths and their use in high-speed optoelectronics and photonic devices that find extensive applications in communication and computation technologies and devices.
This book will consist of chapters that are an elegant mix of reviews and current developments on the subject that will be useful both to an expert on the subject as well as a newcomer to this area of research.

Introducing your Author Service Manager

Ms. Ana Cink

As an Author Service Manager my responsibilities include monitoring and facilitating all publishing activities for authors and editors. From chapter submission and review, to approval and revision, copyediting and design, until final publication, I work closely with authors and editors to ensure a simple and easy publishing process. I maintain constant and effective communication with authors, editors and reviewers, which allows for a level of personal support that enables contributors to fully commit and concentrate on the chapters they are writing, editing, or reviewing. I assist authors in the preparation of their full chapter submissions and track important deadlines and ensure they are met. I help to coordinate internal processes such as linguistic review, and monitor the technical aspects of the process. As an ASM I am also involved in the acquisition of editors. Whether that be identifying an exceptional author and proposing an editorship collaboration, or contacting researchers who would like the opportunity to work with IntechOpen, I establish and help manage author and editor acquisition and contact.
