Course description and aims

This course focuses on the understanding of the dielectric materials and organic devices. Topics include microscopic origin of the polarization, relationship with macroscopic dielectric constant, dielectric dispersion, electronic conduction in the dielectrics and the application of the dielectric materials. And also include fundamentals of organic semiconductor, electronic conduction mechanism, and various organic device applications. The course enables students to understand and acquire the fundamentals of dielectric materials and devices.
Dielectrics are one of the key materials to fabricate electronic devices. Organic semiconductor basically has a nature of dielectric materials because of low carrier density. Therefore the deep understanding of the dielectric materials is also necessary to study such state-of-art devices. I hope students have an interest in the electronic phenomena in various materials.

Student learning outcomes

By the end of this course, students will be able to:
1) Understand the polarization of material, the origin of dielectric constant and dielectric dispersion.
2) Give specific applications of dielectric materials.
3) Explain the model of electronic conduction in the dielectrics and organic semiconductors.
4) Explain the operating principles of various organic devices.
