Regis (M)

• Principles of Photonics and Optoelectronics
• Electronic and Magnetic Properties
• Materials Engineering Issues
• Technology

Fundamental aspects of electrical, optical and magnetic properties of organic small molecules and polymers (synthetic and biological) will be discussed in several lectures. The lectures will offer reviews which cover terminology, sample preparation, measurement techniques, and applications. The classical materials science theme, wherein synthesis and processing determine structure and composition and these in turn determine properties and performance, will be a focus of the presentations. The tutorial will benefit particularly those individuals with little prior experience and who wish to more deeply appreciate the exciting and fast-paced research activity in this area which will be the focus of Symposium W.
